CVE-2026-44985
CVE-2026-44985 is a security vulnerability in github.com/amir20/dozzle. O3 Security confirms whether CVE-2026-44985 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Dozzle: Cross-Site WebSocket Hijacking (CSWSH) on exec/attach endpoints bypasses authentication

Description
Dozzle is a realtime log viewer for docker containers. Prior to 10.5.2, he WebSocket upgrader for the /exec and /attach endpoints uses CheckOrigin: func(r *http.Request) bool { return true }, accepting upgrade requests from any origin. Combined with the JWT cookie using SameSite: Lax, this enables Cross-Site WebSocket Hijacking (CSWSH). An attacker hosting a page on a same-site origin (e.g., a sibling subdomain, or another service on localhost) can initiate a WebSocket connection to the exec endpoint that carries the victim's valid JWT cookie, gaining interactive shell access in any container the victim is authorized to access. This vulnerability is fixed in 10.5.2.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/amir20/dozzle. 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 github.com/amir20/dozzle has shipped for CVE-2026-44985 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-2026-44985 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-2026-44985. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
