CVE-2026-76648 — Red Hat
HIGHCVE-2026-76648 is a high-severity (CVSS 8.5) CWE-862 vulnerability. No vendor fix is recorded yet; mitigation options are listed below.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2026-76648 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Description
CopyAPIView (awx/awx/api/generics.py:873) sets permission_classes = (IsAuthenticated,), so DRF's get_object() performs no object-level RBAC. The get() handler (lines 988–991) explicitly guards with request.user.can_access(obj.class, 'read', obj) — but post() (lines 1001–1010) does not. POST only checks:
can_access(model, 'add', create_kwargs_check)
can_access(model, 'copy_related', obj)
For JobTemplate, can_add (awx/awx/main/access.py:1465–1520) gates on
inventory.use_role + project.use_role + execution_environment.read_role — resource-level roles that do not imply read on the source JT — and can_copy_related (1522–1534) checks only credentials.use_role. None of these imply the caller can read the source JT.
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-2026-76648 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Reduce reachability while you patch: restrict network access to the service to trusted sources, disable or gate the affected component where your deployment allows it, and add a WAF/IPS signature if one exists for CVE-2026-76648. O3's runtime protection blocks the cwe-862 flaw at execution, which holds the line on hosts you cannot patch immediately.
How O3 protects you
O3 detects and blocks CVE-2026-76648 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-2026-76648. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
