21.2.19→21.2.20Angular: Sanitization bypass via directive host bindings on concrete host elements in @angular/core and @angular/compiler
CVE-2026-88057 / GHSA-hh8m-fm6v-7cvg
More information
Details
Angular automatically sanitizes untrusted values bound to security-sensitive DOM sinks (such as
href,src,action,xlink:href, anddata) to protect against Cross-Site Scripting (XSS).Prior to the fix, the Angular compiler determined the
SecurityContextfor directive host bindings (host: {'[attr.href]': 'value'}or@HostBinding('attr.href')) based solely on the declaring directive or component selector at compile time, rather than the concrete host element that the directive was applied to.When a directive with a security-sensitive host binding was applied to a different concrete host element—such as through:
hostDirectivescomposition,createComponentwith customhostElementor dynamic directives),<svg:a>,<math>), or:not(...)),the compiler either failed to associate a sanitizer with the host binding or attached an incorrect security context. As a result, untrusted inputs (e.g.
javascript:...URLs) bound via the host binding would be written to the DOM attribute without passing through Angular's built-in sanitizer.Impact
An attacker capable of controlling the value bound to an affected directive host binding could execute arbitrary JavaScript in the user's browser context (Cross-Site Scripting).
Patches
This issue has been resolved in versions:
22.1.021.2.2020.3.28Workarounds
Ensure that any user-controlled values assigned to properties bound via directive host bindings are explicitly sanitized using
DomSanitizer.sanitize(SecurityContext.URL, ...)before assignment, or restrict the input to validated safe URL schemes (e.g.http://,https://).Severity
