It permits a brute\u2011force attack that can recover the key for an encrypted PDF, allowing an attacker to read the document\u2019s hidden content. The weakness involves impaired key management (CWE-326) and use of an insufficient cryptographic algorithm (CWE-334). The result is disclosure of confidential information that was intended to be protected by encryption.", "risk_and_exploitability": "The vulnerability scores a moderate severity. The chance of widespread exploitation is low, and it is not listed in the CISA Known Exploited Vulnerabilities catalog.
