Versions prior to 2.31.1 contain a low impact and limited cross-site scripting (XSS) vulnerability. The code for XSS payload is always visible, but an attacker can use other techniques to hide the code the victim sees. If the application uses the `execHash` option and executes code from URL, the attacker can use this URL to execute their code. The scope is limited because the javascript attribute used is added to span tag, so no automatic execution like with `onerror` on images is possible. This issue is fixed in version 2.31.1. As a workaround, the user can use formatting that wrap whole user input and its no op. The code for this workaround is available in the GitHub Security Advisory. The fix will only work when user of the library is not using different formatters (e.g. to highlight code in different way).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79","CWE-80"],"references":["https://github.com/jcubic/jquery.terminal/commit/77eb044d0896e990d48a9157f0bc6648f81a84b5","https://github.com/jcubic/jquery.terminal/issues/727","https://github.com/jcubic/jquery.terminal/releases/tag/2.31.1","https://github.com/jcubic/jquery.terminal/security/advisories/GHSA-x9r5-jxvq-4387","https://github.com/jcubic/jquery.terminal/commit/77eb044d0896e990d48a9157f0bc6648f81a84b5"],"products":["jquery.terminal_project:jquery.terminal"],"source":"nvd","synced_at":"2026-10-19T21:26:33.761856376+00:00"},"epss":{"cve":"CVE-2021-43862","score":0.01071,"percentile":0.64893,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-x9r5-jxvq-4387","url":"https://osv.dev/vulnerability/GHSA-x9r5-jxvq-4387","summary":"jquery.terminal self XSS on user input","modified":"2026-07-08T06:28:13.777334456Z","packages":[{"ecosystem":"npm","name":"jquery.terminal","purl":"pkg:npm/jquery.terminal","ranges":["<2.31.1"],"fixed":["2.31.1"]}]}],"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).
