CVE-2026-78360
Description
A missing authorization flaw was found in Anitya. The user deletion endpoint checks that the caller is logged in but does not check that the caller is an administrator. Any authenticated user can delete arbitrary user accounts, including administrator accounts, which can remove administrative access to the service.
Statement
This vulnerability is rated as Important because any authenticated user can delete arbitrary Anitya users, including administrators, over the network with no extra conditions. Anitya is Fedora infrastructure (release-monitoring.org) maintained by the Fedora Infrastructure team. newcli found no Red Hat product streams shipping this component. Red Hat products are not affected.
Mitigation
There is no complete mitigation. Risk can be reduced by blocking the URL path pattern /users/*/delete at the reverse proxy (Apache or nginx) until a patch is available. That also blocks administrators from deleting users in the web UI; those operations would need to be done in the database if required.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data; Read Files or Directories
An attacker could read sensitive data, either by reading the data directly from a data store that is not restricted, or by accessing insufficiently-protected, privileged functionality to read the data.
Integrity
Technical Impact: Modify Application Data; Modify Files or Directories
An attacker could modify sensitive data, either by writing the data directly to a data store that is not restricted, or by accessing insufficiently-protected, privileged functionality to write the data.
Access Control
Technical Impact: Gain Privileges or Assume Identity; Bypass Protection Mechanism
An attacker could gain privileges by modifying or reading critical data directly, or by accessing privileged functionality.
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
An attacker could gain unauthorized access to resources on the system and excessively consume those resources, leading to a denial of service.
Acknowledgements
Red Hat would like to thank Arpit Jain (Independent security researcher) for reporting this issue.
