From 1.14.3 until 1.23.1, jsoup's HTML parser could incorrectly handle a malformed tag name ending in a control character, causing the tag to acquire the parsing behavior of a different element. When a custom Safelist permits certain raw-text elements, this misparsing can cause content that should remain inert text to be emitted as active markup after serialization, potentially resulting in cross-site scripting. jsoup's built-in Safelists are not affected. This issue is fixed in version 1.23.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","score":4.7},"cwes":["CWE-79"],"references":["https://github.com/jhy/jsoup/commit/92f1aca552548b484bc7d4b94c51e48b8e6eca70","https://github.com/jhy/jsoup/issues/2538","https://github.com/jhy/jsoup/releases/tag/jsoup-1.23.1","https://github.com/jhy/jsoup/security/advisories/GHSA-pmhh-3w7g-xqp8"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-71497","score":0.00296,"percentile":0.22008,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-pmhh-3w7g-xqp8","url":"https://osv.dev/vulnerability/GHSA-pmhh-3w7g-xqp8","summary":"jsoup: Cleaner may expose markup with custom raw-text elements","modified":"2026-09-10T03:50:53.809983880Z","packages":[{"ecosystem":"Maven","name":"org.jsoup:jsoup","purl":"pkg:maven/org.jsoup/jsoup","ranges":[">=1.14.3 <1.23.1"],"fixed":["1.23.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
