{"cve":"CVE-2025-52553","nvd":{"published":"2025-06-27T15:15:25.143","modified":"2026-06-17T09:36:39.850","status":"Analyzed","description":"authentik is an open-source identity provider. After authorizing access to a RAC endpoint, authentik creates a token which is used for a single connection and is sent to the client in the URL. This token is intended to only be valid for the session of the user who authorized the connection, however this check is missing in versions prior to 2025.6.3 and 2025.4.3. When, for example, using RAC during a screenshare, a malicious user could access the same session by copying the URL from the shown browser. authentik 2025.4.3 and 2025.6.3 fix this issue. As a workaround, it is recommended to decrease the duration a token is valid for (in the RAC Provider settings, set Connection expiry to `minutes=5` for example). The maintainers of authentik also recommend enabling the option Delete authorization on disconnect.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","score":5.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6},"cwes":["CWE-287"],"references":["https://github.com/goauthentik/authentik/commit/0e07414e9739b318cff9401a413a5fe849545325","https://github.com/goauthentik/authentik/commit/65373ab21711d58147b5cb9276c5b5876baaa5eb","https://github.com/goauthentik/authentik/commit/7100d3c6741853f1cfe3ea2073ba01823ab55caa","https://github.com/goauthentik/authentik/security/advisories/GHSA-wr3v-9p2c-chx7"],"products":["goauthentik:authentik"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2025-52553","score":0.00522,"percentile":0.44326,"date":"2026-10-31"},"kev":null,"osv":[],"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).
