Security Vulnerabilities
PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT is_pem_format is affected because lazy PEM regular expression backtracks extensively. This occurs when a certificate-like input contains repeated BEGIN markers without a matching END marker. As a result, is_pem_format performs unbounded backtracking while searching for a PEM end marker. Consequently, an attacker can cause intensive CPU consumption. This issue is fixed in version 2.14.0.

PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT get_signing_key_from_jwt is affected because unknown kid misses force refreshes without a negative cache or minimum refresh interval. This occurs when unauthenticated tokens repeatedly use the same unknown kid or varying kid values absent from the cached JWKS. As a result, each cache miss causes PyJWKClient to refresh the JWKS. Consequently, attacker traffic can amplify outbound requests to the configured JWKS endpoint. This issue is fixed in version 2.14.0.

PyJWT is a Python implementation of JSON Web Token standards. From 2.0.0a1 until 2.15.0, PyJWT PyJWKClient.get_signing_key_from_jwt is affected because payload parser catches ValueError but not RecursionError. This occurs when an attacker-controlled recursively nested payload reaches json.loads. As a result, documented PyJWT exception handling does not contain the failure. Consequently, an unauthenticated request can raise an exception that may produce an HTTP 500 response. The advisory-defined affected implementation also includes jwt/api_jwt.py, verify_signature=False. This issue is fixed in version 2.15.0.

CVE-2026-86950
An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 26.7.1 and iPadOS 26.7.1, macOS Sequoia 15.8.1, macOS Tahoe 26.7.1. Processing a maliciously crafted file may lead to arbitrary code execution. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27.

Joomla Extension - ordasoft.com - Unauthenticated SQL Injection in Book Library (Free) < 6.4.6 - site/booklibrary.php’s books() function reads the field and direction request parameters and passes each through a function called protectInjectionWithoutQuote(), whose only real protection is a keyword blacklist that, on detecting the literal substring select, wraps the value in $db->quote() instead of rejecting it. The value is then concatenated directly into an unquoted ORDER BY clause, a position where quoting provides no protection at all. Reaching the vulnerable code path requires two conditions: a first request to prime session-stored sort defaults, and a trailing decoy comment (-- xselect) that satisfies the blacklist’s substring check without altering the payload’s effect.

Joomla Extension - ordasoft.com - Reflected Cross-Site Scripting in Book Library (Free) < 6.4.6 - The public book-detail page template, site/views/view_book/tmpl/default.php, echoes the raw title request parameter directly into a double-quoted HTML attribute with no escaping function of any kind (echo $_REQUEST["title"];). A value containing a double quote closes the attribute early and allows arbitrary HTML/JavaScript to follow.

FreePBX is an open source IP PBX. Prior to version 17.0.9, authenticated users who are authorized to access the GraphQL api module interface of FreePBX are able to execute arbitrary shell commands. Authenticated access to the api module is required. The PBX API module's documentation generator accepts an authenticated host parameter and uses it to build a shell command. The code path validates the generated OAuth access token before execution, but it does not validate or escape host. Compromise results in authenticated arbitrary shell command execution as the FreePBX web/PBX service user (typically asterisk.). This issue has been patched in version 17.0.9.

FreePBX is an open source IP PBX. Prior to versions 16.0.40 and 17.0.7, a critical remote code execution (RCE) vulnerability exists in the superfecta module due to unsafe inclusion of arbitrary PHP files, allowing authenticated attackers to execute arbitrary PHP code on the server with the privileges of the web server user. Authentication with a known username is required. The vulnerability is rooted in the options and save_options cases in the Superfecta module's AJAX handler. The code dynamically includes PHP files from the sources/ directory based on user-supplied input. This allows an attacker to execute arbitrary code when combined with arbitrary directory creation (e.g., via the backup module) and file uploads that reveal full paths (e.g., via the soundlang module). This issue has been patched in versions 16.0.40 and 17.0.7.

FreePBX is an open source IP PBX. Prior to versions 16.0.39 and 17.0.7, users authenticated via User Control Panel (UCP) are able to execute arbitrary commands on the PBX as the webserver user (typically asterisk) using specially crafted HTTP strings. Authenticated access to UCP is required. Note that this is often more common for less-privileged users to have UCP access vs. the Administrator Control Panel (ACP) access (which is usually FreePBX higher-level administrator accounts only). Insufficient sanitization of certain URL parameters utilized by UCP did not fully account for malicious strings in these fields. This could result in binaries being executed on the host server by carefully chaining commands. This issue has been patched in versions 16.0.39 and 17.0.7.
