Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict the affected network interface to trusted sources where business-safe.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Gitea Gitea and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

CVE-2026-105267 · CSAF 2.0 · revision 3 · finalRed Hat Product Securitycode.gitea.io/gitea: Gitea: Unauthorized release deletion via tag deletion endpoint
The vendor explicitly states that these products are not affected by this CVE.
- All currently supported Red Hat products
- Summary
- A flaw was found in Gitea. The web endpoint used for deleting repository tags shares request handling logic with release deletion without verifying if the target is an ordinary tag. An authenticated collaborator with code write permissions can exploit this flaw to bypass release access controls and permanently delete published repository releases and their attachments.
- Remediation
- No remediation text is recorded.
High technical severity; prioritise exposed affected systems while verifying vendor guidance.
Patch available01
What, why and how
The Gitea web route for deleting tags (`POST /{owner}/{repo}/tags/delete`) requires only write access to the Code unit, but shares its handler with release deletion and did not check that the target was a plain tag. A collaborator with Code write access and without Releases write access could permanently delete published releases of that repository, including their attachments. Protected tag rules covering the release tag still blocked the deletion.
What
The Gitea web route for deleting tags (`POST /{owner}/{repo}/tags/delete`) requires only write access to the Code unit, but shares its handler with release deletion and did not check that the target was a plain tag. A collaborator with Code write access and without Releases write access could permanently delete published releases of that repository, including their attachments. Protected tag rules covering the release tag still blocked the deletion.
Why
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
How
An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
- Likely attack path
- a network path → Incorrect Permission Assignment for Critical Resource → cause the confidentiality, integrity or availability impact described by the vendor

- Privileges required
- Low: a basic authenticated account is required

CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-732 ↗
CWE-732: Incorrect Permission Assignment for Critical Resource. The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.

- No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.

Patch and workaround
Operational remediation based on structured source evidence.
- Status
?
Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change. - Patch available
- Affected
- Gitea: ≤ 28.0.0
- Action
- Review the linked authoritative reference and apply the recorded fixed release appropriate to the affected product branch.
- Workaround
- No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
