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-2026-54267/ (Markdown: https://insights.sbomify.com/CVE-2026-54267/index.md)","id":"CVE-2026-54267","markdown":"https://insights.sbomify.com/CVE-2026-54267/index.md","name":"CVE-2026-54267","record":{"aliases":["CLSA-2026-1791202115","CLSA-2026-1791202437","CLSA-2026-1791202982","CLSA-2026-1792160934","CLSA-2026-1792161412","CLSA-2026-1792161413","CLSA-2026-1792163807","CLSA-2026-1792163808","CLSA-2026-1792163809","CLSA-2026-1792208373","CLSA-2026-1792208374","CLSA-2026-1792208375","CLSA-2026-1792250416","CLSA-2026-1792250417","CLSA-2026-1792250418","CLSA-2026-1792281554","CLSA-2026-1792281555","CLSA-2026-1792281557","CLSA-2026-1792325789","CLSA-2026-1792325791","CLSA-2026-1792325792","CLSA-2026-1792345539","CLSA-2026-1792345541","CLSA-2026-1792345543","CLSA-2026-1792357651","CLSA-2026-1792357653","CLSA-2026-1792357654","CLSA-2026-1792366811","CLSA-2026-1792366812","CLSA-2026-1792366813","CLSA-2026-1792371904","CLSA-2026-1792371905","CLSA-2026-1792371907","CLSA-2026-1792375975","CLSA-2026-1792375976","CLSA-2026-1792375977","CLSA-2026-1792380287","CLSA-2026-1792380288","CLSA-2026-1792380289","CLSA-2026-1792382842","CLSA-2026-1792382843","CLSA-2026-1792382844","CLSA-2026-1792386335","CLSA-2026-1792386336","CLSA-2026-1792386337","DEBIAN-CVE-2026-54267","GHSA-rgjc-h3x7-9mwg","UBUNTU-CVE-2026-54267"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Angular web framework","requires_auth":"none","summary":"Attackers can hijack Angular SSR hydration state via DOM clobbering to inject malicious scripts or poison cached responses, requiring specific binding patterns.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"angular","vendor":"angular"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-471","name":"Modification of Assumed-Immutable Data (MAID)"}],"description":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.1, 21.2.17, and 20.3.25, to optimize client-side bootstrap in Server-Side Rendered (SSR) environments, Angular supports Hydration via provideClientHydration(). During SSR, Angular serializes the application's runtime state (such as cached HttpClient responses) and outputs it into the HTML stream as a \u003cscript\u003e tag with a predictable identifier. During client bootstrap, Angular recovers this state by looking up the element via document.getElementById('ng-state') and parsing its text content. Because the DOM element lookup for the state container is predictable and relies solely on the ID selector (ng-state), it is susceptible to DOM Clobbering. If the application binds untrusted user input or CMS content to element properties such as id (e.g., \u003cdiv [id]=\"userInput\"\u003e or \u003ca id=\"ng-state\"\u003e) before the genuine \u003cscript\u003e tag is parsed by the browser, the attacker-controlled element takes precedence in the DOM lookup. During hydration, when Angular calls document.getElementById('ng-state'), the browser returns the attacker's clobbered element. Angular then attempts to parse the text content or attributes of this clobbered element as JSON. This vulnerability is fixed in 22.0.1, 21.2.17, and 20.3.25.","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":"Angular Client Hydration DOM Clobbering \u0026 Response-Cache Poisoning","id":"CVE-2026-54267","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":8,"n_references":3,"next":{"headline":"Angular: Denial of Service (DoS) via OOM in Date Formatting (formatDate)","id":"CVE-2026-54268"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["19.2.25"],"package":"@angular/core","purl":null,"source":"GHSA-rgjc-h3x7-9mwg"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["19.2.25"],"package":"@angular/core","purl":"pkg:npm/%40angular/core","source":"GHSA-rgjc-h3x7-9mwg"},{"ecosystem":"npm","fixed":["20.3.25"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/core","purl":null,"source":"GHSA-rgjc-h3x7-9mwg"},{"ecosystem":"npm","fixed":["20.3.25"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/core","purl":"pkg:npm/%40angular/core","source":"GHSA-rgjc-h3x7-9mwg"},{"ecosystem":"npm","fixed":["21.2.17"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/core","purl":null,"source":"GHSA-rgjc-h3x7-9mwg"},{"ecosystem":"npm","fixed":["21.2.17"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/core","purl":"pkg:npm/%40angular/core","source":"GHSA-rgjc-h3x7-9mwg"},{"ecosystem":"npm","fixed":["22.0.1"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/core","purl":null,"source":"GHSA-rgjc-h3x7-9mwg"},{"ecosystem":"npm","fixed":["22.0.1"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/core","purl":"pkg:npm/%40angular/core","source":"GHSA-rgjc-h3x7-9mwg"}],"prev":{"headline":"Angular: Weak 32-Bit Cache Key Hashing in `HttpTransferCache` Leading to Cross-Request Data Leakage and State Poisoning","id":"CVE-2026-54266"},"products":["angular"],"published":"2026-06-22","related":[{"cvss_score":8.8,"headline":"Angular: Cache-Key Ambiguity in HttpTransferCache Leading to Cross-Request Response Reuse and State Poisoning","id":"CVE-2026-68945","kev_date_added":null,"published":"2026-08-03"},{"cvss_score":8.8,"headline":"Angular: SSRF via Hostname Hijacking in @angular/platform-server","id":"CVE-2026-46417","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":8.8,"headline":"Angular: URL Parser Differential in @angular/platform-server leading to SSRF Allowlist Bypass","id":"CVE-2026-50168","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":8.8,"headline":"Angular: Weak 32-Bit Cache Key Hashing in `HttpTransferCache` Leading to Cross-Request Data Leakage and State Poisoning","id":"CVE-2026-54266","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":8.7,"headline":"Angular: SSRF via protocol-relative and backslash URLs in Angular Platform-Server","id":"CVE-2026-41423","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":8.6,"headline":"Angular: SSRF and Cross-Origin Credential Disclosure via URL Resolution Discrepancy in SSR","id":"CVE-2026-88056","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Angular: SSR XSS via Unescaped Processing Instruction (\u003c?...?\u003e) Nodes in Fallback Raw-Content Elements","id":"CVE-2026-88058","kev_date_added":null,"published":"2026-09-10"}],"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":"2026-06-22","vendors":["angular"]},"summary":"Attackers can hijack Angular SSR hydration state via DOM clobbering to inject malicious scripts or poison cached responses, requiring specific binding patterns.","url":"https://insights.sbomify.com/CVE-2026-54267/"}
