Description
A vulnerability was identified in jaychouchannel Tourism-Management-System up to 229956e20dbd4a80eeff14535e44d3099502af09. The affected element is an unknown function of the file travel/src/main/java/com/controller/UsersController.java of the component User Register Endpoint. Such manipulation of the argument UsersEntity leads to improper privilege management. The attack can be launched remotely. The exploit is publicly available and might be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The name of the patch is 84d8ec384f669df3985293dab293bb7b477efa64. Applying a patch is advised to resolve this issue.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. 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 the affected component has shipped for CVE-2026-90523 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-2026-90523 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-2026-90523. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
