Prior to 0.5.0b3.dev100, the packages.js template at src/pyload/webui/app/themes/modern/templates/js/packages.js:172 interpolates a stored link URL into a template literal inside single-quoted HTML and then writes the result to the DOM via $(div).html(html). No escaping runs between the API value and innerHTML. An attacker (Alice) who can submit a package link puts a single quote plus event handler into the URL, breaks out of the attribute, and executes JavaScript in every operator's browser that opens the downloads view. The theme does not set a Content Security Policy that restricts inline script or event handlers. This vulnerability is fixed in 0.5.0b3.dev100.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","score":8.7},"cwes":["CWE-79"],"references":["https://github.com/pyload/pyload/security/advisories/GHSA-fcjq-435v-jx94","https://github.com/pyload/pyload/security/advisories/GHSA-fcjq-435v-jx94"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-45348","score":0.00199,"percentile":0.09747,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-fcjq-435v-jx94","url":"https://osv.dev/vulnerability/GHSA-fcjq-435v-jx94","summary":"pyLoad is vulnerable to stored XSS in Downloads view via unsanitized link URL in packages.js template literal","modified":"2026-07-13T16:43:43.232645032Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<=0.5.0b3.dev99"],"fixed":[]}]},{"id":"PYSEC-2026-2994","url":"https://osv.dev/vulnerability/PYSEC-2026-2994","summary":"pyLoad is vulnerable to stored XSS in Downloads view via unsanitized link URL in packages.js template literal","modified":"2026-07-13T16:32:41.275106245Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<=0.5.0b3.dev99"],"fixed":[]}]}],"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).
