Prior to version 0.6.3, a Cross-Site Scripting (XSS) vulnerability exists in the {% attrs %} template tag of the slippers Django package. When a context variable containing untrusted data is passed to {% attrs %}, the value is interpolated into an HTML attribute string without escaping, allowing an attacker to break out of the attribute context and inject arbitrary HTML or JavaScript into the rendered page. This issue has been patched in version 0.6.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/mixxorz/slippers/commit/16cc4ef4fa8ad2f7aee30798f16c3e7b653423b2","https://github.com/mixxorz/slippers/releases/tag/0.6.3","https://github.com/mixxorz/slippers/security/advisories/GHSA-w7rv-gfp4-j9j3"],"products":["django:slippers"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34231","score":0.00235,"percentile":0.14562,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w7rv-gfp4-j9j3","url":"https://osv.dev/vulnerability/GHSA-w7rv-gfp4-j9j3","summary":"Slippers Vulnerable to Cross-Site Scripting (XSS) in `attrs` Template Tag","modified":"2026-07-13T07:26:50.491874512Z","packages":[{"ecosystem":"PyPI","name":"slippers","purl":"pkg:pypi/slippers","ranges":["<0.6.3"],"fixed":["0.6.3"]}]},{"id":"PYSEC-2026-2279","url":"https://osv.dev/vulnerability/PYSEC-2026-2279","summary":"","modified":"2026-07-13T07:15:42.377432380Z","packages":[{"ecosystem":"PyPI","name":"slippers","purl":"pkg:pypi/slippers","ranges":["<0.6.3"],"fixed":["0.6.3"]}]}],"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).
