CVE-2026-57246
When dealing with abnormally constructed objects, there is a lack of argument validation; JavaScript triggers signature verification, but the signature plugin does not perform validation when copying the abnormal string, causing the application to crash.
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.
