1 technique across 1 tactic: Privilege Escalation

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Exploitation requires a valid authenticated TYPO3 backend account of any privilege level (PR:L); the consent-history and statistics routes fail to check whether the backend user has access to the module or the requested page, so even a minimally privileged editor can reach them. There are no special feature-enablement or non-default-configuration prerequisites noted in the advisory - the flaw is in the routes themselves as shipped. The principal limiting factor is that unauthenticated outsiders cannot exploit it: an attacker must first hold backend credentials, making this primarily an insider or post-credential-compromise exposure; impact is confined to disclosure of cookie-consent history/statistics data across sites, with no integrity or availability effect.

Impact

This is a medium-severity information disclosure issue best characterized as a real but bounded priority rather than an urgent fire. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N, 5.3) is internally consistent with the description: network-reachable, low attack complexity, but requiring low-level privileges (PR:L) - i.e., any authenticated backend user. The confidentiality-only impact (VC:L, no integrity or availability impact) matches a CWE-862 missing-authorization flaw that leaks consent history/statistics. No EPSS score, KEV listing, or POC was provided in the input, so there is no public exploit identified at time of analysis and no evidence of active exploitation; the risk is therefore driven almost entirely by the authorization model rather than by observed threat activity. The key limiting factor is the authentication requirement - an attacker must already hold valid (even minimally privileged) backend credentials, which makes this far more relevant as an insider/privilege-boundary issue or a post-compromise escalation than as a mass-exploitable internet-facing bug. No signals conflict: all available data points consistently to a low-privilege, confidentiality-only exposure. Missing data to note: no affected/fixed version range was supplied beyond the CPE wildcard, and no EPSS/KEV/POC telemetry was provided to gauge real-world interest.

Exploit ScenarioDerived

An attacker who has obtained any TYPO3 backend account - for example a low-privilege editor, or an outsider who phished or guessed weak credentials - directly requests the consent-history and statistics routes. Because these routes never verify module or page access, the attacker retrieves cookie-consent data for any site in the installation, including sites they were never authorized to see. No public exploit code was identified at time of analysis, and the attack requires only ordinary authenticated HTTP requests.

AnalysisAIv1 – Oct 20, 2026

Missing authorization in the Sgalinski Cookie Consent extension for TYPO3 allows any authenticated backend user, regardless of role or module permissions, to read cookie-consent history and statistics for any site in the installation. The exposure is limited to confidentiality of consent data and requires valid backend credentials, so it is primarily an insider or post-compromise risk rather than an unauthenticated attack path. No public exploit code or confirmed active exploitation was identified at time of analysis.

RemediationAI

Patch status is not confirmed from the available data, and no exact fixed version was provided; consult TYPO3-EXT-SA-2026-029 (https://typo3.org/security/advisory/typo3-ext-sa-2026-029) for the vendor update and apply it as soon as it is available. Until then, reduce exposure by limiting TYPO3 backend accounts to trusted staff, removing dormant accounts, and reviewing backend user groups for unnecessary privileges; these measures lower the number of potential exploiters but do not fix the missing route-level authorization. If the extension's consent history and statistics are not required, disable or remove the extension, accepting loss of that functionality. Where operationally feasible, restrict access to the TYPO3 backend behind a VPN or IP-allowlisting reverse proxy and monitor logs for unusual requests to consent-history or statistics routes; the trade-off is reduced flexibility for legitimate remote administrators.

Technical ContextAI · show details

The affected component is the TYPO3 extension sgalinski_cookie_consent, which exposes backend routes for consent history and statistics. CWE-862 (Missing Authorization) describes the root cause: the route handlers do not verify that the authenticated backend user has access to the module or to the specific page whose consent data is requested. TYPO3's backend authorization model relies on module and page permissions; because these checks are absent, any backend account-including a minimally privileged editor-can query data across sites. The CPE cpe:2.3:a:typo3:extension_"sgalinski_cookie_consent":*:*:*:*:*:*:*:* identifies the extension, and the vendor advisory is TYPO3-EXT-SA-2026-029.

DescriptionCVE.org

The routes that provide consent history and statistics data did not check whether the backend user had access to the module or to the requested page. Any authenticated backend user, regardless of permissions, could therefore retrieve consent data of any site in the installation.
