Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-30956 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @oneuptime/common (npm): affected all versions; fixed in 10.0.21\n- @oneuptime/common (npm): affected all versions; fixed in 10.0.21\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-2026-30956/ (Markdown: https://insights.sbomify.com/CVE-2026-30956/index.md)","id":"CVE-2026-30956","markdown":"https://insights.sbomify.com/CVE-2026-30956/index.md","name":"CVE-2026-30956","record":{"aliases":["GHSA-r5v6-2599-9g3m"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OneUptime monitoring platform","requires_auth":"low_privilege","summary":"Low-privileged users can bypass tenant isolation and authorization checks via forged headers, leading to cross-tenant data exposure and full account takeover.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"oneuptime","vendor":"hackerbay"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-285","name":"Improper Authorization"}],"description":"OneUptime is a solution for monitoring and managing online services. Prior to 10.0.21, a low‑privileged user can bypass authorization and tenant isolation in OneUptime v10.0.20 and earlier by sending a forged is-multi-tenant-query header together with a controlled projectid header. Because the server trusts this client-supplied header, internal permission checks in BasePermission are skipped and tenant scoping is disabled. This allows attackers to access project data belonging to other tenants, read sensitive User fields via nested relations, leak plaintext resetPasswordToken, and reset the victim’s password and fully take over the account. This results in cross‑tenant data exposure and full account takeover. This vulnerability is fixed in 10.0.21.","ecosystems":["npm"],"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":"OneUptime has authorization bypass via client‑controlled is-multi-tenant-query header","id":"CVE-2026-30956","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"OneUptime Synthetic Monitor RCE via exposed Playwright browser object","id":"CVE-2026-30957"},"packages":[{"ecosystem":"npm","fixed":["10.0.21"],"introduced":["0"],"last_affected":[],"package":"@oneuptime/common","purl":null,"source":"GHSA-r5v6-2599-9g3m"},{"ecosystem":"npm","fixed":["10.0.21"],"introduced":["0"],"last_affected":[],"package":"@oneuptime/common","purl":"pkg:npm/%40oneuptime/common","source":"GHSA-r5v6-2599-9g3m"}],"prev":{"headline":"Gokapi vulnerable to DoS in E2E Metadata Parser","id":"CVE-2026-30955"},"products":["oneuptime"],"published":"2026-03-10","related":[{"cvss_score":10,"headline":"Code injection in oneuptime","id":"CVE-2026-33396","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":10,"headline":"OneUptime ClickHouse SQL Injection via Aggregate Query Parameters","id":"CVE-2026-32306","kev_date_added":null,"published":"2026-03-12"},{"cvss_score":10,"headline":"OneUptime Synthetic Monitor RCE via exposed Playwright browser object","id":"CVE-2026-30957","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":10,"headline":"OneUptime Affected by Unsandboxed Code Execution in Probe Allows Any Project Member to Achieve RCE","id":"CVE-2026-30887","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":10,"headline":"OneUptime Synthetic Monitor RCE via exposed Playwright browser object","id":"CVE-2026-30921","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":10,"headline":"OneUptime: OS Command Injection in Probe NetworkPathMonitor via unsanitized destination in traceroute exec()","id":"CVE-2026-27728","kev_date_added":null,"published":"2026-02-25"}],"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":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-10","vendors":["OneUptime"]},"summary":"Low-privileged users can bypass tenant isolation and authorization checks via forged headers, leading to cross-tenant data exposure and full account takeover.","url":"https://insights.sbomify.com/CVE-2026-30956/"}
