Description
Capgo before 12.244.1 contains a cross-tenant integrity vulnerability in the metadata-cleaning worker that trusts image object keys from mutable database rows without validating ownership. An authenticated attacker can place a victim tenant's image key in a row they control, causing the service-role worker to download and re-upload that object with sanitized metadata. Attackers can silently modify metadata in cross-tenant image objects by supplying known victim keys during authorized row updates, bypassing storage access controls through the confused-deputy metadata worker.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`). Because exploitation targets the running service rather than your application code, O3 also flags the exploit behaviour from runtime telemetry and egress traffic.
Remediation status
No fixed release is recorded for CVE-2026-100614 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used. O3's runtime protection blocks the cwe-639 flaw at execution, which holds the line on hosts you cannot patch immediately.
How O3 protects you
O3 detects and blocks CVE-2026-100614 exploitation at runtime with eBPF exploit-chain detection, plus L7 egress monitoring that catches a post-exploitation callback and cuts the attacker's outbound channel.
Tailored to CVE-2026-100614. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
