Prior to 22.0.1, 21.2.17, and 20.3.25, an issue in the @angular/compiler package allows bypassing DOM property sanitization through the use of two-way property bindings. Specifically, when a native DOM property that requires sanitization (such as innerHTML, srcdoc, src, href, data, or sandbox) is bound using the two-way binding syntax (e.g., [(innerHTML)]=\"value\" or bindon-innerHTML=\"value\"), the Angular template compiler failed to apply the appropriate schema-derived sanitizer resolution to the TwoWayProperty operation. As a result, native two-way DOM bindings were emitted without the required sanitizer function, whereas equivalent one-way bindings would be properly sanitized. This flaw enables an attacker who can control the value of a two-way bound sensitive property to bypass Angular's built-in sanitization logic, potentially leading to client-side Cross-Site Scripting (XSS). 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: Two-Way Property Binding Sanitization Bypass (XSS)","id":"CVE-2026-54265","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: Weak 32-Bit Cache Key Hashing in `HttpTransferCache` Leading to Cross-Request Data Leakage and State Poisoning","id":"CVE-2026-54266"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["19.2.25"],"package":"@angular/compiler","purl":null,"source":"GHSA-58w9-8g37-x9v5"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["19.2.25"],"package":"@angular/compiler","purl":"pkg:npm/%40angular/compiler","source":"GHSA-58w9-8g37-x9v5"},{"ecosystem":"npm","fixed":["20.3.25"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/compiler","purl":null,"source":"GHSA-58w9-8g37-x9v5"},{"ecosystem":"npm","fixed":["20.3.25"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/compiler","purl":"pkg:npm/%40angular/compiler","source":"GHSA-58w9-8g37-x9v5"},{"ecosystem":"npm","fixed":["21.2.17"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/compiler","purl":null,"source":"GHSA-58w9-8g37-x9v5"},{"ecosystem":"npm","fixed":["21.2.17"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/compiler","purl":"pkg:npm/%40angular/compiler","source":"GHSA-58w9-8g37-x9v5"},{"ecosystem":"npm","fixed":["22.0.1"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/compiler","purl":null,"source":"GHSA-58w9-8g37-x9v5"},{"ecosystem":"npm","fixed":["22.0.1"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/compiler","purl":"pkg:npm/%40angular/compiler","source":"GHSA-58w9-8g37-x9v5"}],"prev":{"headline":"Angular: Sensitive Header Leakage on Cross-Origin Redirects in Angular Service Worker","id":"CVE-2026-54264"},"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":"partial"},"state":"PUBLISHED","updated":"2026-06-22","vendors":["angular"]},"summary":"Attackers can bypass Angular's DOM sanitization via two-way property bindings to execute arbitrary JavaScript, leading to Cross-Site Scripting.","url":"https://insights.sbomify.com/CVE-2026-54265/"}
