Description
Vikunja is a todo-app to organize your life. Prior to 1.1.0, TaskGlanceTooltip.vue temporarily creates a div and sets the innerHtml to the description. Since there is no escaping on either the server or client side, a malicious user can share a project, create a malicious task, and cause an XSS on hover. This vulnerability is fixed in 1.1.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for code.vikunja.io/api. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of code.vikunja.io/api has shipped for CVE-2026-25935 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 pinpoints whether CVE-2026-25935 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-25935. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
