{"apiVersion":"1.0","identifier":"CVE-2026-76212","description":"phpMyFAQ before 4.1.7, when configured to use PostgreSQL via the native pgsql PHP extension, declares an incorrect LIKE ESCAPE character (-=-) in the Search/Database/Pgsql.php backend while escapeLikeWildcards() escapes user input with the -|- prefix. As a result, wildcard escaping is a no-op and user-supplied % and _ characters remain active LIKE wildcards. An unauthenticated attacker can submit such characters in the public FAQ search form to force maximally broad pattern matches and expensive sequential scans, resulting in a denial of service. The PDO PostgreSQL backend is not affected, and quotes remain escaped so this does not enable quote-breaking SQL injection or data exfiltration.","publishedAt":"2026-08-19T14:17:46","lastModifiedAt":"2026-08-25T03:16:57","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-76212","cvssScore":5.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","epssProbability":0.00299,"riskScore":0.54,"affectedProduct":"phpMyFAQ","affectedVersions":"<4.1.7","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-76212","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-76212","en":"https://www.redsauce.net/en/cves/CVE-2026-76212","fr":"https://www.redsauce.net/fr/cves/CVE-2026-76212","pt":"https://www.redsauce.net/pt/cves/CVE-2026-76212","de":"https://www.redsauce.net/de/cves/CVE-2026-76212","sk":"https://www.redsauce.net/sk/cves/CVE-2026-76212","el":"https://www.redsauce.net/el/cves/CVE-2026-76212"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-76212"}}
