An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-107840 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/jhaals/yopass (Go): affected all versions; fixed in 0.0.0-20260727191436-61e31ead04a4\n- github.com/jhaals/yopass (Go): affected all versions; fixed in 0.0.0-20260727191436-61e31ead04a4\n- github.com/jhaals/yopass (Go): affected all versions; fixed in 0.0.0-20260727191436-61e31ead04a4\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-2026-107840/ (Markdown: https://insights.sbomify.com/CVE-2026-107840/index.md)","id":"CVE-2026-107840","markdown":"https://insights.sbomify.com/CVE-2026-107840/index.md","name":"CVE-2026-107840","record":{"aliases":["GHSA-6r69-c6wg-7g8m","GO-2026-6720"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Secret sharing service","requires_auth":"none","summary":"Unauthenticated attackers can exhaust server memory by sending requests with unique HTTP methods, causing denial of service in yopass.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"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-400","name":"Uncontrolled Resource Consumption"}],"description":"yopass is a service for securely sharing secrets, passwords, and files. Prior to version 14.7.0, the Prometheus metrics middleware in pkg/server/server.go uses the attacker-controlled r.Method value directly as the method label for yopass_http_requests_total and yopass_http_request_duration_seconds. Because the catch-all route accepts arbitrary HTTP method tokens, an unauthenticated remote attacker can submit many unique methods and create metric series that the Prometheus registry never evicts. The resulting monotonic memory growth can OOM-kill the process, while the expanding registry also degrades /metrics scrape latency and can blind monitoring. This issue is fixed in version 14.7.0.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"yopass Prometheus metrics middleware allows remote memory exhaustion through unbounded method labels","id":"CVE-2026-107840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":3,"n_references":5,"next":{"headline":"pacioli: A submit consent marker licensed cancellation of caller-named pre-existing documents","id":"CVE-2026-107841"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20260727191436-61e31ead04a4"],"introduced":["0"],"last_affected":[],"package":"github.com/jhaals/yopass","purl":null,"source":"GHSA-6r69-c6wg-7g8m"},{"ecosystem":"Go","fixed":["0.0.0-20260727191436-61e31ead04a4"],"introduced":["0"],"last_affected":[],"package":"github.com/jhaals/yopass","purl":"pkg:golang/github.com/jhaals/yopass","source":"GHSA-6r69-c6wg-7g8m"},{"ecosystem":"Go","fixed":["0.0.0-20260727191436-61e31ead04a4"],"introduced":["0"],"last_affected":[],"package":"github.com/jhaals/yopass","purl":"pkg:golang/github.com/jhaals/yopass","source":"GO-2026-6720"}],"prev":{"headline":"ageLANServer: Unbounded JSON Array Allocation in AoE3 Cloud `getFileURL` Endpoint Leads to Remote Denial of Service","id":"CVE-2026-107839"},"products":["yopass"],"published":"2026-10-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-09","vendors":["jhaals"]},"summary":"Unauthenticated attackers can exhaust server memory by sending requests with unique HTTP methods, causing denial of service in yopass.","url":"https://insights.sbomify.com/CVE-2026-107840/"}
