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-2026-33538 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- parse-server (npm): affected all versions; fixed in 8.6.58\n- parse-server (npm): affected all versions; fixed in 8.6.58\n- parse-server (npm): affected from 9.0.0; fixed in 9.6.0-alpha.52\n- parse-server (npm): affected from 9.0.0; fixed in 9.6.0-alpha.52\n- parse (Bitnami): affected all versions; fixed in 8.6.58, 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-2026-33538/ (Markdown: https://insights.sbomify.com/CVE-2026-33538/index.md)","id":"CVE-2026-33538","markdown":"https://insights.sbomify.com/CVE-2026-33538/index.md","name":"CVE-2026-33538","record":{"aliases":["BIT-parse-2026-33538","GHSA-g4cf-xj29-wqqr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Parse Server backend","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service by triggering full database scans via requests to unconfigured authentication providers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"parse-server","vendor":"parseplatform"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.58 and 9.6.0-alpha.52, an unauthenticated attacker can cause denial of service by sending authentication requests with arbitrary, unconfigured provider names. The server executes a database query for each unconfigured provider before rejecting the request, and since no database index exists for unconfigured providers, each request triggers a full collection scan on the user database. This can be parallelized to saturate database resources. This issue has been patched in versions 8.6.58 and 9.6.0-alpha.52.","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: Denial of service via unindexed database query for unconfigured auth providers","id":"CVE-2026-33538","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"parseplatform:parse-server","products":["parseplatform:parse-server"],"type":"denial_of_service","year":"2026"},"n_packages":5,"n_references":5,"next":{"headline":"Parse Server: SQL injection via aggregate and distinct field names in PostgreSQL adapter","id":"CVE-2026-33539"},"packages":[{"ecosystem":"Bitnami","fixed":["8.6.58","9.6.0"],"introduced":["0","9.0.0"],"last_affected":[],"package":"parse","purl":"pkg:bitnami/parse","source":"BIT-parse-2026-33538"},{"ecosystem":"npm","fixed":["8.6.58"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-g4cf-xj29-wqqr"},{"ecosystem":"npm","fixed":["8.6.58"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-g4cf-xj29-wqqr"},{"ecosystem":"npm","fixed":["9.6.0-alpha.52"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-g4cf-xj29-wqqr"},{"ecosystem":"npm","fixed":["9.6.0-alpha.52"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-g4cf-xj29-wqqr"}],"prev":{"headline":"Lychee has SSRF bypass via incomplete IP validation in Photo::fromUrl — loopback and link-local IPs not blocked","id":"CVE-2026-33537"},"products":["parse-server"],"published":"2026-03-24","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":"2026-03-24","vendors":["parse-community"]},"summary":"Unauthenticated attackers can cause denial of service by triggering full database scans via requests to unconfigured authentication providers.","url":"https://insights.sbomify.com/CVE-2026-33538/"}
