{"schemaVersion":3,"id":"CVE-2026-76212","aliases":[],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-08-19T14:01:58.591Z","modified":"2026-08-25T01:55:21.857Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.9,"severity":"medium","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":6.9,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":6.9,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00428,"percentile":0.35986,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.12000000000000001,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00308},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00428,"percentile":0.35986}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00308,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00428,"percentile":null},{"date":"20
