RUSTSEC-2026-0187 Stack overflow in lopdf via deeply nested PDF objects

lopdf::Document::loadmem and the other load entry points parses nested PDF arrays and dictionaries with unbounded recursion. A small crafted PDF whose Catalog contains a deeply nested array /X … , on the order of 10,000 levels exhausts the call stack and aborts the process with SIGABRT. Because...

SurrealDB: Denial of Service via deep operator chains

An authenticated user could crash a SurrealDB server with a single query containing a long chain of operators. Such a query — for example RETURN 1 + 1 + 1 + ... with tens of thousands of terms — is parsed into an expression tree one level deep per operator. Because the chain is flat and the pratt...

GHSA-9C83-RR99-VFWJ MCPVault: PathFilter restricted directories (.git/.obsidian/node_modules) only denied at vault root, not nested

PathFilter's deny-list glob patterns are anchored, so .git, .obsidian, and nodemodules were only blocked at the vault root. Nested copies inside the vault e.g. tools/cli/nodemodules/..., tools/somerepo/.git/config, a nested .obsidian/ were fully traversable via isAllowed/isAllowedForListing...

CVE-2026-49346

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in de265imagegetbuffer libde265/image.cc:128. The overflow wraps the plane allocation size to a sma...

GHSA-CGXM-VR2F-6FJ8 parse-server: Denial of service via exponential-time processing of deeply nested query operators

Impact Parse Server is vulnerable to denial of service. A remote attacker can send a single, small query 1 KB containing deeply nested query condition operators. Parse Server processes the nested structure with exponential time complexity, which blocks the Node.js event loop and makes the server...
