{"id":"CVE-2022-23599","aliases":["GHSA-g4c2-ghfg-g5rh","PYSEC-2022-21"],"url":"https://o3.security/vulnerability/CVE-2022-23599","summary":"Cross-site Scripting and Open Redirect in Products.ATContentTypes","details":"Products.ATContentTypes are the core content types for Plone 2.1 - 4.3. Versions of Plone that are dependent on Products.ATContentTypes prior to version 3.0.6 are vulnerable to reflected cross site scripting and open redirect when an attacker can get a compromised version of the image_view_fullscreen page in a cache, for example in Varnish. The technique is known as cache poisoning. Any later visitor can get redirected when clicking on a link on this page. Usually only anonymous users are affected, but this depends on the user's cache settings. Version 3.0.6 of Products.ATContentTypes has been released with a fix. This version works on Plone 5.2, Python 2 only. As a workaround, make sure the image_view_fullscreen page is not stored in the cache. More information about the vulnerability and cvmitigation measures is available in the GitHub Security Advisory.","published":"2022-01-28T22:00:15Z","modified":"2026-08-12T03:51:23.184716689Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"},"epss":{"score":0.0075,"percentile":0.51802,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"products-atcontenttypes","fixedVersion":"3.0.6"}],"fix":{"url":"https://github.com/plone/Products.ATContentTypes/commit/fc793f88f35a15a68b52e4abed77af0da5fdbab8","label":"plone/Products.ATContentTypes@fc793f8"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23599.json"},{"type":"ADVISORY","url":"https://github.com/plone/Products.ATContentTypes/security/advisories/GHSA-g4c2-ghfg-g5rh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23599"},{"type":"FIX","url":"https://github.com/plone/Products.ATContentTypes/commit/fc793f88f35a15a68b52e4abed77af0da5fdbab8"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:23.184716689Z"}}
