This occurs because of a case-sensitivity desync between the authorization classifier and the request dispatcher: the gitHTTPIsPull function compares the Git action verb case-sensitively and defaults to pull (read access) for any unrecognized string, whereas the request dispatcher lowercases the same verb before routing it to the receive-pack handler. Capitalizing a single letter in the URL (e.g. info/Refs instead of info/refs, or git-receive-Pack instead of git-receive-pack) causes the classifier to misidentify a push as a pull, granting only read-level authorization, whereas the dispatcher routes it to the write handler. An authenticated read-only collaborator can exploit this to push to a private repository, creating, updating, or deleting refs."}],"metrics":[{"cvssV4_0":{"Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","Safety":"NOT_DEFINED","attackComplexity":"LOW","attackRequirements":"NONE","attackVector":"NETWORK","baseScore":7.1,"baseSeverity":"HIGH","privilegesRequired":"LOW","providerUrgency":"NOT_DEFINED","subAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"LOW","userInteraction":"NONE","valueDensity":"NOT_DEFINED","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:L/SA:N","version":"4.0","vulnAvailabilityImpact":"LOW","vulnConfidentialityImpact":"NONE","vulnIntegrityImpact":"HIGH","vulnerabilityResponseEffort":"NOT_DEFINED"},"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}]}],"problemTypes":[{"descriptions":[{"cweId":"CWE-178","description":"CWE-178 Improper Handling of Case Sensitivity","lang":"en","type":"CWE"}]}],"providerMetadata":{"orgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","shortName":"mitre","dateUpdated":"2026-11-06T18:03:53.415Z"},"references":[{"tags":["related"],"url":"https://github.com/gogs/gogs/security/advisories/GHSA-wmfg-5p4h-5fw3"},{"tags":["product"],"url":"https://github.com/gogs/gogs/blob/3ba8aca90e17e5410b7e8b227c9f29256ac3e875/internal/route/repo/http.go#L415-L418"},{"tags":["product"],"url":"https://github.com/gogs/gogs/blob/3ba8aca90e17e5410b7e8b227c9f29256ac3e875/internal/route/repo/http.go#L64-L68"},{"tags":["third-party-advisory"],"url":"https://humanoid.sh/blog/gogs-cve-2026-123012/"}],"solutions":[{"lang":"en","supportingMedia":[{"base64":false,"type":"text/html","value":"No patch available.
