CVE-2026-5941
Parsing logic flaws cause non-signature data to be misidentified as valid signatures when processing malformed form field hierarchies, leading to invalid memory writes and program crashes during internal data structure construction.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
