{"schemaVersion":3,"id":"CVE-2026-34973","aliases":[],"status":"published","duplicateOf":null,"title":"phpMyFAQ has a LIKE Wildcard Injection in Search.php — Unescaped % and _ Metacharacters Enable Broad Content Disclosure","description":"phpMyFAQ is an open source FAQ web application. Prior to version 4.1.1, the searchCustomPages() method in phpmyfaq/src/phpMyFAQ/Search.php uses real_escape_string() (via escape()) to sanitize the search term before embedding it in LIKE clauses. However, real_escape_string() does not escape SQL LIKE metacharacters % (match any sequence) and _ (match any single character). An unauthenticated attacker can inject these wildcards into search queries, causing them to match unintended records — including content that was not meant to be surfaced — resulting in information disclosure. This issue has been patched in version 4.1.1.","dates":{"published":"2026-04-02T14:47:22.775Z","modified":"2026-04-03T18:24:15.944Z","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:L/VI:N/VA:N/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:L/VI:N/VA:N/SC:N/SI:N/SA:N","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:L/VI:N/VA:N/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:L/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00385,"percentile":0.3141,"severity":"low","asOf":"2026-10-22T00:00:00.000Z","change":{"pp":0.049,"baselineDate":"2026-09-22T00:00:00.000Z","baselineScore":0.00336},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-22T00:00:00.000Z","score":0.00385,"percentile":0.3141}],"last30":[{"date":"2026-09-22T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00385,"percentile":null},{"date":"2026-10-05T00:0
