Description
This security bulletin contains information about 3 vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2026-54265)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]
The vulnerability allows a remote attacker to execute arbitrary JavaScript in the target user's browser.
The vulnerability exists due to improper neutralization of input in the @angular/compiler TwoWayProperty operation when processing two-way bindings on sensitive native DOM properties. A remote attacker can supply an unsanitized user-controlled property value to execute arbitrary JavaScript in the target user's browser.
Exploitation requires a user to interact with content containing the injected value.
2) Cross-site scripting (CVE-ID: CVE-2026-69151)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data within event-handler attributes in Angular i18n. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
3) Cross-site scripting (CVE-ID: CVE-2026-50557)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]
The vulnerability allows a remote attacker to execute arbitrary JavaScript in the target user's browser context.
The vulnerability exists due to improper element sanitization and validation in the Angular template preparser when compiling user-controlled templates with custom namespace prefixes. A remote attacker can inject a namespaced script element to execute arbitrary JavaScript in the target user's browser context.
The application must process user-controlled template input at runtime and must not separately sanitize that input before passing it to the Angular compiler.
