CVE-2026-54622 — django CMS: Clipboard copy IDOR discloses unauthorized plugin content
django CMS is an easy-to-use and developer-friendly enterprise content management system powered by Django. Prior to 5.0.8, the copy_plugins endpoint in cms/admin/placeholderadmin.py authorizes only the destination clipboard. The _copy_plugin_to_clipboard and _copy_placeholder_to_clipboard paths accept source_placeholder_id and source_plugin_id values but use has_copy_plugins_permission and check_source only for the requesting user’s clipboard, without validating the source placeholder. Under CMS_PERMISSION, a staff user with the global add permission for a plugin type can copy plugins from an unauthorized page or placeholder into the user’s clipboard and read secret text, link names, and URLs. This issue is fixed in versions 5.0.8.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.4% (30-day exploitation probability)+5
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Django-cms Django-cms).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
- Audit administrative actions and access to resources outside each user’s normal pattern.

What should defenders know first?
CVE-2026-54622 is "django CMS: Clipboard copy IDOR discloses unauthorized plugin content", rated Medium. It affects Django-cms (Django-cms); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.5 describes technical severity. EPSS 0.42% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
