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-2026-33042 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- parse-server (npm): affected all versions; fixed in 8.6.49\n- parse-server (npm): affected all versions; fixed in 8.6.49\n- parse-server (npm): affected from 9.0.0; fixed in 9.6.0-alpha.29\n- parse-server (npm): affected from 9.0.0; fixed in 9.6.0-alpha.29\n- parse (Bitnami): affected all versions; fixed in 8.6.49, 9.6.0\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-2026-33042/ (Markdown: https://insights.sbomify.com/CVE-2026-33042/index.md)","id":"CVE-2026-33042","markdown":"https://insights.sbomify.com/CVE-2026-33042/index.md","name":"CVE-2026-33042","record":{"aliases":["BIT-parse-2026-33042","GHSA-wjqw-r9x4-j59v"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Parse Server backend","requires_auth":"none","summary":"Attackers can create authenticated user sessions without credentials by sending empty authData, bypassing signup requirements in Parse Server.","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":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.29 and 8.6.49, a user can sign up without providing credentials by sending an empty `authData` object, bypassing the username and password requirement. This allows the creation of authenticated sessions without proper credentials, even when anonymous users are disabled. The fix in 9.6.0-alpha.29 and 8.6.49 ensures that empty or non-actionable `authData` is treated the same as absent `authData` for the purpose of credential validation on new user creation. Username and password are now required when no valid auth provider data is present. As a workaround, use a Cloud Code `beforeSave` trigger on the `_User` class to reject signups where `authData` is empty and no username/password is provided.","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 affected by empty authData bypassing credential requirement on signup","id":"CVE-2026-33042","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":3,"next":{"headline":"AVideo affected by Session Hijacking via Unauthenticated Session ID Disclosure with Permissive CORS","id":"CVE-2026-33043"},"packages":[{"ecosystem":"Bitnami","fixed":["8.6.49","9.6.0"],"introduced":["0","9.0.0"],"last_affected":[],"package":"parse","purl":"pkg:bitnami/parse","source":"BIT-parse-2026-33042"},{"ecosystem":"npm","fixed":["8.6.49"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-wjqw-r9x4-j59v"},{"ecosystem":"npm","fixed":["8.6.49"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-wjqw-r9x4-j59v"},{"ecosystem":"npm","fixed":["9.6.0-alpha.29"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-wjqw-r9x4-j59v"},{"ecosystem":"npm","fixed":["9.6.0-alpha.29"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-wjqw-r9x4-j59v"}],"prev":{"headline":"AVideo has an Unauthenticated Password Hash Oracle via encryptPass.json.php","id":"CVE-2026-33041"},"products":["parse-server"],"published":"2026-03-18","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-20","vendors":["parse-community"]},"summary":"Attackers can create authenticated user sessions without credentials by sending empty authData, bypassing signup requirements in Parse Server.","url":"https://insights.sbomify.com/CVE-2026-33042/"}
