{"id":"CVE-2022-23598","aliases":["GHSA-jq4p-mq33-w375"],"url":"https://o3.security/vulnerability/CVE-2022-23598","summary":"Reflected XSS vulnerability when rendering error messages in laminas-form","details":"laminas-form is a package for validating and displaying simple and complex forms. When rendering validation error messages via the `formElementErrors()` view helper shipped with laminas-form, many messages will contain the submitted value. However, in laminas-form prior to version 3.1.1, the value was not being escaped for HTML contexts, which could potentially lead to a reflected cross-site scripting attack. Versions 3.1.1 and above contain a patch to mitigate the vulnerability. A workaround is available. One may manually place code at the top of a view script where one calls the `formElementErrors()` view helper. More information about this workaround is available on the GitHub Security Advisory.","published":"2022-01-28T22:00:16Z","modified":"2026-08-12T03:51:40.330711805Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"epss":{"score":0.00989,"percentile":0.59337,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Packagist","name":"laminas/laminas-form","fixedVersion":"3.1.1"},{"ecosystem":"Packagist","name":"laminas/laminas-form","fixedVersion":"3.0.2"},{"ecosystem":"Packagist","name":"laminas/laminas-form","fixedVersion":"2.17.1"}],"fix":{"url":"https://github.com/laminas/laminas-form/commit/43005a3ec4c2292d4f825273768d9b884acbca37","label":"laminas/laminas-form@43005a3"},"references":[{"type":"ADVISORY","url":"https://getlaminas.org/security/advisory/LP-2022-01"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23598.json"},{"type":"ADVISORY","url":"https://github.com/laminas/laminas-form/security/advisories/GHSA-jq4p-mq33-w375"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CFF6WJ5I7PSEBRF6I753WKE2BXFBGQXE/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SLNABVK26CE4PFL57VLY242FW3QY4CPC/"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23598"},{"type":"FIX","url":"https://github.com/laminas/laminas-form/commit/43005a3ec4c2292d4f825273768d9b884acbca37"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:40.330711805Z"}}
