Plone.app.dexterity versions through 3.2.2, 4.0.0 through 4.1.2, and 5.0.0, and plone.app.contenttypes versions through 3.0.11, 4.0.0 through 4.0.9, and 5.0.0 are vulnerable to denial of service because an authenticated user can create content with excessively long titles, descriptions, or uploaded-file names, causing Plone to become unresponsive and potentially making the resulting content difficult to edit or delete. The vulnerability is patched in plone.app.dexterity versions 3.2.3, 4.1.3, and 5.0.1, and in plone.app.contenttypes versions 3.0.12, 4.0.10, and 5.0.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-400"],"references":["https://github.com/plone/plone.app.contenttypes/commit/13dc98a578341aac24a1e65fd9bc7ac8a07d168a","https://github.com/plone/plone.app.contenttypes/commit/21bae6ebe424689eeac9a5884fc0da35f4944e63","https://github.com/plone/plone.app.contenttypes/commit/639c0619f371df578e69ec94e5ca98e60fd6ed58","https://github.com/plone/plone.app.contenttypes/commit/7bb03e8ec6c6bd0e645f445b0755e85a51afb158","https://github.com/plone/plone.app.contenttypes/commit/bed1547d4f8b1fc995f2c76f30ba5f20276a8ad6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-57576","score":0.00762,"percentile":0.55375,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-5426-92w4-wvhv","url":"https://osv.dev/vulnerability/GHSA-5426-92w4-wvhv","summary":"plone.app.dexterity has a Denial of Service due to excessive title or description length","modified":"2026-10-01T17:55:54.152002091Z","packages":[{"ecosystem":"PyPI","name":"plone-app-dexterity","purl":"pkg:pypi/plone-app-dexterity","ranges":[">=5.0.0 <5.0.1"],"fixed":["5.0.1"]},{"ecosystem":"PyPI","name":"plone-app-dexterity","purl":"pkg:pypi/plone-app-dexterity","ranges":[">=4.0.0 <4.1.3"],"fixed":["4.1.3"]},{"ecosystem":"PyPI","name":"plone-app-dexterity","purl":"pkg:pypi/plone-app-dexterity","ranges":["<3.2.3"],"fixed":["3.2.3"]}]},{"id":"PYSEC-2026-4137","url":"https://osv.dev/vulnerability/PYSEC-2026-4137","summary":"plone.app.dexterity has a Denial of Service due to excessive title or description length","modified":"2026-10-01T17:45:13.658700091Z","packages":[{"ecosystem":"PyPI","name":"plone-app-dexterity","purl":"pkg:pypi/plone-app-dexterity","ranges":["<3.2.3",">=4.0.0 <4.1.3",">=5.0.0 <5.0.1"],"fixed":["3.2.3","4.1.3","5.0.1"]}]}],"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).
