CVE-2026-48488: CWE-328: Use of Weak Hash in thorsten phpMyFAQ
phpMyFAQ versions prior to 4.1.4 use SHA-1, a cryptographically broken hash algorithm, for hashing attachment passwords. SHA-1 has been vulnerable to collision attacks since 2017. This weakness was addressed in version 4.1.4.
AI Analysis
Technical Summary
The vulnerability CVE-2026-48488 in phpMyFAQ involves the use of the weak SHA-1 hashing algorithm for attachment passwords in versions before 4.1.4. SHA-1 is considered cryptographically broken due to its susceptibility to collision attacks, which have been publicly demonstrated since 2017. The issue is resolved in phpMyFAQ version 4.1.4, which replaces 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 exploit collision vulnerabilities to compromise password integrity. However, the CVSS score of 2.7 and the low severity rating indicate that the overall risk is low, and no known exploits are reported in the wild.
Mitigation Recommendations
Upgrade phpMyFAQ to version 4.1.4 or later, where the weak SHA-1 hashing has been replaced with a stronger algorithm. No other mitigation is indicated or required.
