An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-28789 exists.\n\nAffected packages and fixed versions:\n- github.com/OliveTin/OliveTin (Go): affected all versions; no fix listed\n- github.com/OliveTin/OliveTin (Go): affected all versions; fixed in 0.0.0-20260301235225-f044d90d5525c\n- github.com/OliveTin/OliveTin (Go): affected all versions; fixed in 0.0.0-20260301235225-f044d90d5525c\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-28789/ (Markdown: https://insights.sbomify.com/CVE-2026-28789/index.md)","id":"CVE-2026-28789","markdown":"https://insights.sbomify.com/CVE-2026-28789/index.md","name":"CVE-2026-28789","record":{"aliases":["GHSA-45m3-398w-m2m9","GO-2026-4586"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"OliveTin web interface","requires_auth":"none","summary":"Unauthenticated attackers can crash OliveTin by triggering a race condition in OAuth2 state handling, requiring OAuth2 to be enabled.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"olivetin","vendor":"olivetin"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-662","name":"Improper Synchronization"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.10.3, an unauthenticated denial-of-service vulnerability exists in OliveTin’s OAuth2 login flow.
