Patch Tuesday, May 2026 Edition
Artificial intelligence platforms may be just as susceptible to social engineering as human beings, but they are proving remarkably good at finding security vulnerabilities in human-made computer code. That reality is on full display this month with some of the more widely-used software makers -- including Apple, Google, Microsoft, Mozilla and Oracle -- fixing near record volumes of security bugs, and/or quickening the tempo of their patch releases.

Canvas Breach Disrupts Schools & Colleges Nationwide
An ongoing data extortion attack targeting the widely-used education technology platform Canvas disrupted classes and coursework at school districts and universities across the United States today, after a cybercrime group defaced the service's login page with a ransom demand that threatened to leak data from 275 million students and faculty across nearly 9,000 educational institutions.

This is due to an incomplete blocklist that correctly restricts capability meta keys for the primary site (e.g., `wp_capabilities`, `wp_user_level`) but fails to block the equivalent meta keys for any other subsite in a WordPress Multisite network (e.g., `wp_2_capabilities`, `wp_2_user_level`), allowing these keys to pass the `in_array()` check and be written directly to user meta via `update_user_meta()`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their privileges to Administrator on any subsite within the Multisite network by submitting a crafted profile update to `/wp-admin/profile.php`. Exploitation requires that an administrator has previously imported a CSV file containing multisite-prefixed capability column headers and has enabled the 'Show fields in profile?' option, which causes those keys to be stored in the `acui_columns` option and exposed as editable fields on the user profile page. 2026-05-02 8.8 CVE-2026-7641 https://www.wordfence.com/threat-intel/vulnerabilities/id/368cff00-6a86-443e-aec4-4115a229a3c1?source=cvehttps://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/columns.php#L221https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/columns.php#L221https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/columns.php#L198https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/columns.php#L198https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/helper.php#L150https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/helper.php#L150https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/trunk/classes/multisite.php#L21https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.8/classes/multisite.php#L21https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/columns.php#L221https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/columns.php#L198https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/helper.php#L150https://plugins.trac.wordpress.org/browser/import-users-from-csv-with-meta/tags/2.0.6/classes/multisite.php#L21https://plugins.trac.wordpress.org/changeset/3515646  Cozmoslabs--Profile Builder Pro The Profile Builder Pro plugin for WordPress is vulnerable to PHP Object Injection in all versions up to and including 3.14.5. This is due to the use of PHP's maybe_unserialize() function on the attacker-controlled 'args' POST parameter within the wppb_request_users_pins_action_callback() AJAX handler, which lacked any nonce verification, type checking, or input validation before deserialization. Because the handler was registered with both wp_ajax_ and wp_ajax_nopriv_ hooks, it was reachable by completely unauthenticated users. This makes it possible for unauthenticated attackers to inject arbitrary PHP objects into application memory. 2026-05-02 8.1 CVE-2026-7647 https://www.wordfence.com/threat-intel/vulnerabilities/id/c7b897f5-f988-4515-83bc-456f041d7e2e?source=cvehttps://plugins.trac.wordpress.org/browser/profile-builder-pro/trunk/add-ons/user-listing/one-map-listing.php#L271https://plugins.trac.wordpress.org/browser/profile-builder-pro/tags/3.14.5/add-ons/user-listing/one-map-listing.php#L271https://plugins.trac.wordpress.org/browser/profile-builder-pro/trunk/add-ons/user-listing/one-map-listing.php#L13https://plugins.trac.wordpress.org/browser/profile-builder-pro/tags/3.14.5/add-ons/user-listing/one-map-listing.php#L13  Shenzhen Libituo Technology--LBT-T300-HW1 A flaw has been found in Shenzhen Libituo Technology LBT-T300-HW1 up to 1.2.8. This issue affects the function start_single_service of the component Web Management Interface. Executing a manipulation of the argument vpn_pptp_server/vpn_l2tp_server can lead to buffer overflow. The attack can be executed remotely. The vendor was contacted early about this disclosure but did not respond in any way. 2026-05-03 8.8 CVE-2026-7674 VDB-360827 | Shenzhen Libituo Technology LBT-T300-HW1 Web Management start_single_service buffer overflowVDB-360827 | CTI Indicators (IOB, IOC, IOA)Submit #800705 | Libtor Technology lbt-t300-hw1 closure, xreq). The NULL propagation chain through afb-context.c:110 (context- >credentials = afb_cred_addref(NULL)) and afb-cred.c:163 (returns NULL when cred is NULL) confirms that credentials are zeroed before the target API executes. The attacker controls both api and verb parameters via JSON input, allowing execution of any registered API with a NULL credential context. APIs that rely on context- >credentials for authorization decisions may fail open when receiving NULL credentials, enabling privilege escalation. This vulnerability was introduced in commit abbb4599f0b921c6f434b6bd02bcfb277eecf745 on 2018-02-14. 2026-05-01 7.8 CVE-2026-37525 https://gerrit.automotivelinux.org/gerrit/src/app-framework-binderhttps://gist.github.com/sgInnora/8526eedcfd826d05ef1fc45d8f405643  n/a--Automotive Grade Linux (AGL) afb-daemon v19.90.0 AGL app-framework-binder (afb-daemon) through v19.90.0 allows any local process to execute privileged supervision commands (Exit, Do, Sclose, Config, Trace, Debug, Token, slist) without authentication via the abstract Unix socket @urn:AGL:afs:supervision:socket. The on_supervision_call function in src/afb-supervision.c dispatches all 8 commands without any credential verification. The abstract socket has no DAC protection, as acknowledged in the official CAUTION comment in src/afs-supervision.h. This allows a low-privileged local process to kill the daemon (DoS via Exit command), execute arbitrary API calls (via Do command), close arbitrary user sessions (via Sclose command), or leak the entire global configuration (via Config command). The vulnerability was introduced in commit b8c9d5de384efcfa53ebdb3f0053d7b3723777e1 on 2017-06-29. 2026-05-01 7.8 CVE-2026-37526 https://gerrit.automotivelinux.org/gerrit/src/app-framework-binderhttps://gist.github.com/sgInnora/8526eedcfd826d05ef1fc45d8f405643  n/a--Automotive Grade Linux (AGL) aglservice v17.1.12 AGL agl-service-can-low-level thru 17.1.12 contains a heap buffer over-read in the isotp-c library. In isotp_continue_receive (receive.c:87-89), the payload_length for a Single Frame is extracted from a 4-bit nibble in the CAN frame data, yielding values 0-15. However, a standard CAN frame is only 8 bytes, with payload starting at data[1] (7 bytes available). When payload_length exceeds the available data (e.g., nibble=15 but only 7 payload bytes exist), memcpy(message.payload, &data[1], payload_length) reads up to 8 bytes past the end of the data buffer. 2026-05-01 7.1 CVE-2026-37532 https://gerrit.automotivelinux.org/gerrit/apps/agl-service-can-low-levelhttps://gist.github.com/sgInnora/8526eedcfd826d05ef1fc45d8f405643  n/a--Automotive Grade Linux (AGL) isotp-c openxc/isotp-c thru commit 5a5d19245f65189202719321facd49ce6f5d46ac (2021-08-09) contains an out-of-bounds read in the ISO-TP Single Frame receive handler, where the 4-bit payload length nibble is used directly as the memcpy size without validating it against the actual CAN data length.

The vulnerability exists in the GeoNetworking packet processing pipeline where OpenSSL exceptions from ECC point validation (invalid compressed point, point not on curve) are not properly caught by the Router::indicate() call chain. The openssl_wrapper.cpp check() function (line 19) throws openssl::Exception when OpenSSL operations fail. The parser's catch block in parse_secured() should catch these, but the exception escapes through subsequent processing stages (indicate_common, indicate_extended).

The routes do not verify whether the target chart is actually allowed on the public report or whether the governing SharePolicy permits public access. An unauthenticated attacker who knows a chart identifier in a public project can read or export chart data for charts that were intentionally hidden from the report.

The `esc_sql()` function is applied but is ineffective in the `ORDER BY` context because the value is not enclosed in quotes. Additionally, while a `sanitize_sort_arg()` allowlist-based sanitizer was added in version 1.13.18, it is only applied in the AJAX code path (`sanitize_query_args()`) and not in the `render-map.php` or template tag code paths.

This is due to the `SearchResults` hook explicitly calling `stripslashes_deep($_POST)` which removes WordPress magic quotes protection, followed by the unsanitized `map_post_type` value being concatenated into an `IN(...)` clause without `esc_sql()` or `$wpdb- >prepare()`. The 'any' branch of the same code correctly applies `array_map('esc_sql', ...)`, but the else branch does not. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via a time-based blind approach.

This is due to insufficient escaping on the user supplied parameters and lack of sufficient preparation on the existing SQL query. The `esc_sql()` function is applied but is ineffective because the values are placed in an unquoted `IN(...)` / `NOT IN(...)` SQL context - `esc_sql()` only escapes quote characters and provides no protection against parenthesis or SQL keyword injection.

From version 1.0.0 to before version 4.14.4, a heap-based out-of-bounds WRITE occurs in GetAlertData, resulting in writing a NULL byte exactly 1 byte before the start of the buffer allocated by strdup. Due to unsigned integer underflow and pointer arithmetic wrapping, the write lands at offset -1 from the buffer, corrupting heap metadata. A malicious actor can potentially leverage this issue through a compromised agent to cause denial of service or heap corruption by injecting a specially crafted alert into the alerts log file monitored by wazuh-logcollector.

When root-level dtrace attaches to -- or instruments -- that process (via dtrace -p , pid probes, or USDT), the ELF parser reads heap memory beyond the allocated section cache array without any bounds check. This results in an uninitialized/out-of-bounds heap read that can cause a NULL pointer dereference crash of the dtrace process (DoS), or -- depending on heap layout -- a read-then-use of a garbage pointer controlled by adjacent allocations, providing a foothold toward further exploitation in a privileged context. 2026-05-01 4.4 CVE-2026-35233 Oracle Advisory  n/a-- V2Board  v1.7.4 SQL Injection via ORDER BY clause in V2Board thru 1.7.4.

Anti-DDoS Firm Heaped Attacks on Brazilian ISPs
A Brazilian tech firm that specializes in protecting networks from distributed denial-of-service (DDoS) attacks has been enabling a botnet responsible for an extended campaign of massive DDoS attacks against other network operators in Brazil, KrebsOnSecurity has learned. The firm's chief executive says the malicious activity resulted from a security breach and was likely the work of a competitor trying to tarnish his company's public image.
