BIT-DISCOURSE-2026-91119 Discourse: Encode action_code_who in mention URLs

Discourse is an open-source discussion platform. Prior to 2026.1.8, 2026.6.3, 2026.7.2, and 2026.8.0, the topic small-action and nested-activity-log components interpolated the free-form actioncodewho value into mention-link href attributes without URL encoding. A quote-bearing display name could...

BIT-DISCOURSE-2026-84302 Discourse: Non-participant moderators can read, edit, and delete PM content through Discourse AI reviewables

Discourse is an open-source discussion platform. Prior to 2026.1.6, 2026.5.2, 2026.6.1, and 2026.7.0, Discourse AI reviewables associated with private messages could appear in the moderator review queue of a moderator who was not a participant in the message. Reviewable visibility filtering did n...

BIT-LIBPHP-2026-91766 Cross-origin credential leak in HTTP stream wrapper redirects

When the http:// stream wrapper follows a redirect it forwards the user-supplied Authorization, Cookie and Proxy-Authorization headers unchanged, even when the redirect target is a different host, a different port, or a downgrade from HTTPS to HTTP. A server that can steer a redirect therefore...

BIT-LIBPHP-2026-91765 SOAP: Unbounded Recursion in Server-Side cleanup_xml_node

cleanupxmlnode in the SOAP XML parser recurses once per XML nesting level with no depth limit. An unauthenticated attacker can post a SOAP request containing tens of thousands of nested elements to any SoapServer endpoint, exhaust the stack and crash the process. The same unbounded recursion exis...

BIT-LIBPHP-2026-6103 Phar TAR phar_tar_number() Integer Overflow - Archive Entry Injection

phartarnumber parses the octal size field of a TAR header into a uint32t with no overflow check. The field is 11 octal digits wide and holds values up to 0x1FFFFFFFF, so a size above 0xFFFFFFFF silently wraps. The parser then skips the wrong number of data blocks and interprets attacker-controlle...

BIT-LIBPHP-2026-17545 PHP on Windows: Reserved Device Names Are Not Rejected Before File/Stream I/O which can cause DoS

On Windows, PHP's filesystem and stream APIs do not reject reserved device names such as CON, PRN, AUX, NUL, COM1 to COM9, LPT1 to LPT9, CONIN$ and CONOUT$ when they appear as a component of a path. An attacker-controlled filename therefore reaches CreateFileW and opens a device instead of the...

BIT-LIBPHP-2025-14181 Integer overflow to buffer overflow in soap HTTP parsing

The SOAP HTTP client guards its response buffer growth with a check that relies on signed integer overflow, which is undefined behaviour and is not guaranteed to trigger. When the check is optimised away, a malicious SOAP server can make the client allocate a buffer far smaller than the data it...

BIT-LIBPHP-2025-1218 Various packet overreads in mysqlnd_writeprotocol.c

The mysqlnd wire protocol parser reads fields out of server packets before checking that the packet still holds enough bytes for them. A malicious or compromised MySQL server can send a truncated packet and make the client read past the end of the packet buffer, which is undefined behaviour and c...

BIT-KYVERNO-2026-100707 Kyverno before 1.19.1 Namespace Isolation Bypass via Percent-Encoded Path

Kyverno before 1.19.1 contains a namespace isolation bypass in the apiCall context entry of namespaced Policy resources due to inconsistent path interpretation between validation and execution. A low-privilege tenant can use percent-encoded dot-segments in urlPath to bypass namespace checks and...

BIT-KYVERNO-2026-100706 kyverno before 1.19.1 Privilege Escalation via Policy apiCall urlPath

kyverno before 1.19.1 fails to properly validate URL-encoded path segments in Policy apiCall urlPath, allowing namespace tenants to bypass the per-namespace clamp and create objects in other namespaces as the admission-controller ServiceAccount. Attackers can exploit this by using percent-encoded...
