Description
Impact
wallabag versions prior to 2.6.11 were discovered to contain multiple Cross-Site Request Forgery (CSRF) vulnerabilities across several endpoints. An attacker could craft a malicious link or page that, if visited by a logged-in wallabag user, could trick the user's browser into performing unintended actions within their wallabag account without their consent. Additionally, one endpoint affects the login page locale setting.
The affected endpoints allow attackers to potentially perform actions such as:
- Manage API Tokens:
/generate-token/revoke-token
- Manage User Rules:
/tagging-rule/delete/{taggingRule}/ignore-origin-user-rule/delete/{ignoreOriginUserRule}
- Modify User Configuration:
/config/view-mode
- Manage Individual Entries:
/reload/{id}/archive/{id}/star/{id}/delete/{id}/share/{id}/share/delete/{id}
- Manage Tags:
/remove-tag/{entry}/{tag}/tag/search/{filter}/tag/delete/{slug}
- Perform Bulk Actions:
/mass
- Change Interface Language (Login Page):
/locale/{language}
Successfully exploiting these vulnerabilities could lead to unauthorized modification or deletion of user data, configuration changes, token manipulation, or interface changes, depending on the specific endpoint targeted.
This set of vulnerabilities has an aggregated CVSS v3.1 score of 4.3 (Medium).
Users are strongly advised to upgrade their wallabag instance to version 2.6.11 or later to mitigate these vulnerabilities.
Resolution
These vulnerabilities have been addressed in wallabag version 2.6.11. The affected endpoints have been modified to require the HTTP POST method along with a valid CSRF token for state-changing actions, preventing attackers from forcing users' browsers to perform these actions unintentionally.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wallabag/wallabag, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update wallabag/wallabag to 2.6.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5pm7-cp8f-p2c2 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-5pm7-cp8f-p2c2 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-5pm7-cp8f-p2c2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
