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...

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...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the de265imagegetbuffer function when processing a crafted H.265 bitstream containing large SPS dimensions and 16-bit bit depth. An attacker can cause a heap buffer overflow by supplying a specially...
