CVE-2026-48488: CWE-328: Use of Weak Hash in thorsten phpMyFAQ
phpMyFAQ versions prior to 4. 1. 4 use SHA-1 to hash attachment passwords. SHA-1 is a cryptographically broken hash function vulnerable to collision attacks since 2017. This weakness could reduce the security of attachment password hashes. The issue is fixed in version 4. 1. 4.
AI Analysis
Technical Summary
The vulnerability CVE-2026-48488 affects phpMyFAQ, an open source FAQ web application. Versions before 4.1.4 use the SHA-1 hashing algorithm for attachment passwords. SHA-1 is considered weak due to its susceptibility to collision attacks, which have been demonstrated since 2017. This use of a weak hash algorithm is classified under CWE-328. The vulnerability has a low CVSS 4.0 base score of 2.7, reflecting limited impact and exploitability. The vendor fixed the issue in phpMyFAQ version 4.1.4 by replacing SHA-1 with a stronger hashing method.
Potential Impact
The use of SHA-1 for hashing attachment passwords weakens the cryptographic protection of these passwords, potentially allowing attackers to find collisions and compromise password integrity. However, the overall impact is low as indicated by the CVSS score, and no known exploits are reported in the wild.
Mitigation Recommendations
Upgrade phpMyFAQ to version 4.1.4 or later, where the use of SHA-1 for attachment password hashing has been replaced with a stronger algorithm. Patch status is not explicitly stated but the vendor fixed the issue in version 4.1.4, so updating to this version or newer is the recommended remediation.
