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-2026-34532 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- parse-server (npm): affected all versions; fixed in 8.6.67\n- parse-server (npm): affected all versions; fixed in 8.6.67\n- parse-server (npm): affected from 9.0.0; fixed in 9.7.0-alpha.11\n- parse-server (npm): affected from 9.0.0; fixed in 9.7.0-alpha.11\n- parse (Bitnami): affected all versions; fixed in 8.6.67, 9.7.0\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-2026-34532/ (Markdown: https://insights.sbomify.com/CVE-2026-34532/index.md)","id":"CVE-2026-34532","markdown":"https://insights.sbomify.com/CVE-2026-34532/index.md","name":"CVE-2026-34532","record":{"aliases":["BIT-parse-2026-34532","GHSA-vpj2-qq7w-5qq6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Parse Server backend","requires_auth":"none","summary":"Attackers can bypass Cloud Function access controls by manipulating function names, allowing unauthenticated execution of protected backend logic.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"parse-server","vendor":"parseplatform"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.67 and 9.7.0-alpha.11, an attacker can bypass Cloud Function validator access controls by appending \"prototype.constructor\" to the function name in the URL. When a Cloud Function handler is declared using the function keyword and its validator is a plain object or arrow function, the trigger store traversal resolves the handler through its own prototype chain while the validator store fails to mirror this traversal, causing all access control enforcement to be skipped. This allows unauthenticated callers to invoke Cloud Functions that are meant to be protected by validators such as requireUser, requireMaster, or custom validation logic. This issue has been patched in versions 8.6.67 and 9.7.0-alpha.11.","ecosystems":["Bitnami","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":"Parse Server: Cloud function validator bypass via prototype chain traversal","id":"CVE-2026-34532","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"parseplatform:parse-server","products":["parseplatform:parse-server"],"type":"auth_bypass","year":"2026"},"n_packages":5,"n_references":5,"next":{"headline":"iccDEV: UB in CIccCalculatorFunc::ApplySequence()","id":"CVE-2026-34533"},"packages":[{"ecosystem":"Bitnami","fixed":["8.6.67","9.7.0"],"introduced":["0","9.0.0"],"last_affected":[],"package":"parse","purl":"pkg:bitnami/parse","source":"BIT-parse-2026-34532"},{"ecosystem":"npm","fixed":["8.6.67"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-vpj2-qq7w-5qq6"},{"ecosystem":"npm","fixed":["8.6.67"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-vpj2-qq7w-5qq6"},{"ecosystem":"npm","fixed":["9.7.0-alpha.11"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-vpj2-qq7w-5qq6"},{"ecosystem":"npm","fixed":["9.7.0-alpha.11"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-vpj2-qq7w-5qq6"}],"prev":{"headline":"Flask-HTTPAuth invokes token verification callback when missing or empty token was given by client","id":"CVE-2026-34531"},"products":["parse-server"],"published":"2026-03-31","related":[{"cvss_score":10,"headline":"Parse Server role escalation and CLP bypass via direct `_Join` table write","id":"CVE-2026-30966","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":10,"headline":"Parse Server literalizeRegexPart SQL Injection","id":"CVE-2024-27298","kev_date_added":null,"published":"2024-03-01"},{"cvss_score":10,"headline":"Command Injection in Parse server","id":"CVE-2022-24760","kev_date_added":null,"published":"2022-03-11"},{"cvss_score":9.9,"headline":"Parse Server session token exfiltration via `redirectClassNameForKey` query parameter","id":"CVE-2026-30965","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":9.8,"headline":"Parse Server vulnerable to remote code execution via MongoDB BSON parser through prototype pollution","id":"CVE-2023-36475","kev_date_added":null,"published":"2023-06-28"},{"cvss_score":9.8,"headline":"Parse Server vulnerable to Remote Code Execution via prototype pollution in MongoDB BSON parser","id":"CVE-2022-39396","kev_date_added":null,"published":"2022-11-10"},{"cvss_score":9.3,"headline":"Parse Server: Account takeover via operator injection in authentication data identifier","id":"CVE-2026-32248","kev_date_added":null,"published":"2026-03-12"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2026-03-31","vendors":["parse-community"]},"summary":"Attackers can bypass Cloud Function access controls by manipulating function names, allowing unauthenticated execution of protected backend logic.","url":"https://insights.sbomify.com/CVE-2026-34532/"}
