PublishedThe Custom Field Template plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.7.8 via the edit_meta_value due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to delete arbitrary media attachments site-wide by supplying any numeric attachment ID in the file-field parameter alongside the corresponding delete flag, causing content loss and broken pages. Exploitation requires that the attacker's post is governed by a Custom Field Template containing at least one file-type field with the mediaRemove option not enabled, which is the default configuration for file fields.

Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Risk history
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
When does an EPSS score appear as a change?
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
Advisory history
1 saved versionsSee how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
How advisory history works
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
