Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-30948 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- parse-server (npm): affected all versions; fixed in 8.6.17\n- parse-server (npm): affected all versions; fixed in 8.6.17\n- parse-server (npm): affected from 9.0.0; fixed in 9.5.2-alpha.4\n- parse-server (npm): affected from 9.0.0; fixed in 9.5.2-alpha.4\n- parse (Bitnami): affected all versions; fixed in 8.6.17, 9.5.2\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-2026-30948/ (Markdown: https://insights.sbomify.com/CVE-2026-30948/index.md)","id":"CVE-2026-30948","markdown":"https://insights.sbomify.com/CVE-2026-30948/index.md","name":"CVE-2026-30948","record":{"aliases":["BIT-parse-2026-30948","GHSA-hcj7-6gxh-24ww"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Parse Server backend","requires_auth":"low_privilege","summary":"Authenticated users can upload malicious SVG files to execute scripts in the browser, stealing session tokens and taking over accounts.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"parse-server","vendor":"parseplatform"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:N/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2-alpha.4 and 8.6.17, a stored cross-site scripting (XSS) vulnerability allows any authenticated user to upload an SVG file containing JavaScript. The file is served inline with Content-Type: image/svg+xml and without protective headers, causing the browser to execute embedded scripts in the Parse Server origin. This can be exploited to steal session tokens from localStorage and achieve account takeover. The default fileExtensions option blocks HTML file extensions but does not block SVG, which is a well-known XSS vector. All Parse Server deployments where file upload is enabled for authenticated users (the default) are affected. This vulnerability is fixed in 9.5.2-alpha.4 and 8.6.17.","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 has stored cross-site scripting (XSS) via SVG file upload","id":"CVE-2026-30948","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"parseplatform:parse-server","products":["parseplatform:parse-server"],"type":"xss","year":"2026"},"n_packages":5,"n_references":3,"next":{"headline":"Parse Server is missing audience validation in Keycloak authentication adapter","id":"CVE-2026-30949"},"packages":[{"ecosystem":"Bitnami","fixed":["8.6.17","9.5.2"],"introduced":["0","9.0.0"],"last_affected":[],"package":"parse","purl":"pkg:bitnami/parse","source":"BIT-parse-2026-30948"},{"ecosystem":"npm","fixed":["8.6.17"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-hcj7-6gxh-24ww"},{"ecosystem":"npm","fixed":["8.6.17"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-hcj7-6gxh-24ww"},{"ecosystem":"npm","fixed":["9.5.2-alpha.4"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-hcj7-6gxh-24ww"},{"ecosystem":"npm","fixed":["9.5.2-alpha.4"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-hcj7-6gxh-24ww"}],"prev":{"headline":"Parse Server ha a bypass of class-level permissions in LiveQuery","id":"CVE-2026-30947"},"products":["parse-server"],"published":"2026-03-10","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":"partial"},"state":"PUBLISHED","updated":"2026-03-10","vendors":["parse-community"]},"summary":"Authenticated users can upload malicious SVG files to execute scripts in the browser, stealing session tokens and taking over accounts.","url":"https://insights.sbomify.com/CVE-2026-30948/"}
