CVE-2026-112368

An uncontrolled recursion weakness in the BSON decoding logic of the MongoDB PHP driver may allow an unauthenticated party who can supply crafted binary document data to the decoder to exhaust the process stack. This may cause the PHP process using the driver to terminate unexpectedly, resulting ...

CVE-2025-51495

I would like to report a security vulnerability identified in the latest release of Mongoose v7.17. The issue resides in the WebSocket module, specifically within the mgwscb function responsible for handling incoming WebSocket frames. The function is vulnerable to an integer overflow, which may...

CVE-2026-73260

A flaw was found in Mongoose. The built-in Transport Layer Security TLS certificate parser fails to verify that element lengths fit within the remaining certificate buffer, leading to an out-of-bounds memory read. An unauthenticated remote attacker can exploit this vulnerability by presenting a...

CVE-2026-63626

A flaw was found in Mongoose. An unauthenticated adjacent attacker can exploit this issue by sending a specially crafted Point-to-Point Protocol PPP packet containing an oversized length field during IPv6 Control Protocol IPv6CP negotiation. This lack of bounds validation causes out-of-bounds...

CVE-2026-73260

Mongoose is an embedded web server and network library. Prior to 7.23, the built-in TLS certificate parser selected by MGTLSBUILTIN fails to verify that a long-form DER element length fits within the remaining certificate buffer. In mgdertotlv and mgdernext, a peer-controlled length can advance t...

CVE-2026-73252

Mongoose is an embedded web server and network library. Prior to 7.23, the built-in TLS stack selected by MGTLSBUILTIN in src/tlsbuiltin.c accepts a TLS 1.3 record whose decrypted size is exactly the 16-byte authentication tag with no plaintext or ContentType byte. In mgtlsrecvrecord, the msgsz...

CVE-2026-73261
