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-2026-123807/ (Markdown: https://insights.sbomify.com/CVE-2026-123807/index.md)","id":"CVE-2026-123807","markdown":"https://insights.sbomify.com/CVE-2026-123807/index.md","name":"CVE-2026-123807","record":{"aliases":["GHSA-4xm8-rg9h-jhq2"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Signal K Server is a server application that runs on a central hub in a boat. From 2.0.0 until 2.34.0 for Signal K Server and from 1.0.0 until 1.5.3 for @signalk/resources-provider, the v2 REST route GET /signalk/v2/api/resources/:resourceType/:resourceId accepts an unsafe resourceId that can escape the intended resource directory. The route passes the attacker-controlled resourceId through src/api/resources/index.ts to FileStore.getResource() in packages/resources-provider-plugin/src/filestorage.ts without adequate path containment, allowing arbitrary JSON files reachable by the server to be read. Related PUT and DELETE resource operations can write or delete files outside the storage root. Deployments with allow_readonly enabled permit anonymous reads, while other deployments require a readonly user token. Reading security.json exposes the HS256 JWT signing secret and password hashes, allowing an attacker to forge an administrator token. Administrative access to POST /skServer/providers can then create an Execute provider that runs commands with the server process privileges and persists its configuration across restarts. This issue is fixed in Signal K Server 2.34.0 and @signalk/resources-provider 1.5.3.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":"2026-11-12","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-11-12T07:12:05Z","kind":"github_poc","ref":"https://github.com/qianlijaingshan/signalk-audit","stars":0,"title":"Signal K Server resources API path traversal audit (CVE-2026-123807): read JWT secret, forge admin token, verify RCE"}],"tier":"weaponised"},"has_fix":true,"headline":"Signal K resources API path traversal can disclose the JWT signing secret and enable remote code execution","id":"CVE-2026-123807","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"Nuxt UI: UAuthForm / UForm SSR markup omits `method`, leaking credentials via GET if submitted before hydration","id":"CVE-2026-123808"},"nickname":null,"packages":[{"ecosystem":"npm","fixed":["1.5.3"],"introduced":["1.0.0"],"last_affected":[],"package":"@signalk/resources-provider","purl":null,"source":"GHSA-4xm8-rg9h-jhq2"},{"ecosystem":"npm","fixed":["2.34.0"],"introduced":["2.0.0"],"last_affected":[],"package":"signalk-server","purl":null,"source":"GHSA-4xm8-rg9h-jhq2"}],"prev":{"headline":"python-tuf: Platform-dependent delegation path matching","id":"CVE-2026-123806"},"products":["resources-provider","signalk-server"],"published":"2026-11-09","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-11-10","vendors":["@signalk","SignalK"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-123807/"}
