CVE-2026-103820
CAI Content Credential is affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could result in an arbitrary file system write. An attacker could leverage this vulnerability to write to unauthorized files or directories outside of intended restrictions. Exploitation of this issue requires user interaction in that a victim must extract a maliciously crafted file.
