Description
A security flaw has been discovered in liftoff-sr CIPster 1802525be27d33e19a9a83c163e331a1d13b1892. The impacted element is the function CipAttribute::GetAttrData/CipAttribute::SetAttrData of the file ciptypes.h of the component Generic Attribute Logic. Performing a manipulation results in memory corruption. It is possible to initiate the attack remotely. The exploit has been released to the public and may be used for attacks. The patch is named e745d9d4a8ca3a13689066983a1269fe1e567674. It is suggested to install a patch to address 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-2026-76987 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-2026-76987 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-2026-76987. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
