CVE-2026-52810: Gogs: Write to readonly repositories using receive-pack + service=git-upload-pack confusion

Severity: high (CVSS 7.1 v4.0)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.4% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2026-06-24 · updated 2026-06-25
Weakness: CWE-284

Description

Gogs is an open source self-hosted Git service. Prior to 0.14.3, Git smart HTTP authorizes POST …/git-receive-pack using the client-supplied service query string (so ?service=git-upload-pack is evaluated as read access) while routing still runs git receive-pack, allowing push where only read should be allowed. This vulnerability is fixed in 0.14.3.

Affected products

gogs: before 0.14.3
