Package Instance

Cross-Site Scripting via JSONP
JSONP allows untrusted resource URLs, which provides a vector for attack by malicious actors.

XSS in $sanitize in Safari/Firefox
Both Firefox and Safari are vulnerable to XSS if we use an inert document created via `document.implementation.createHTMLDocument()`.

angular vulnerable to regular expression denial of service via the $resource service
All versions of the package angular are vulnerable to Regular Expression Denial of Service (ReDoS) via the $resource service due to the usage of an insecure regular expression. Exploiting this vulnerability is possible by a large carefully-crafted input, which can result in catastrophic backtracking.

Denial of service in $sanitize
Running $sanitize on bad HTML can freeze the browser. The problem occurs with clobbered data; typically the "nextSibling" property on an element is changed to one of it's child node, this makes it impossible to walk the HTML tree and leads to an infinite loop which freezes the browser.

Bypass CSP protection
Extension URIs (`resource://...`) bypass ````Content-Security-Policy```` in Chrome and Firefox and can always be loaded. Now if a site already has a XSS bug, and uses CSP to protect itself, but the user has an extension installed that uses Angular, an attacked can load Angular from the extension, and Angular's auto-bootstrapping can be used to bypass the victim site's CSP protection.

Improper sanitization of the value of the `[srcset]` attribute in `<source>` HTML elements in AngularJS allows attackers to bypass common image source restrictions, which can also lead to a form of  Content Spoofing https://owasp.org/www-community/attacks/Content_Spoofing .

This issue affects all versions of AngularJS.

The AngularJS project is End-of-Life and will not receive any updates to address this issue. For more information see  here https://docs.angularjs.org/misc/version-support-status .

angular vulnerable to regular expression denial of service via the <input type="url"> element
All versions of the package angular are vulnerable to Regular Expression Denial of Service (ReDoS) via the <input type="url"> element due to the usage of an insecure regular expression in the input[url] functionality. Exploiting this vulnerability is possible by a large carefully-crafted input, which can result in catastrophic backtracking.

Code Injection
The attribute usemap can be used as a security exploit.

Cross Site Scripting
On Firefox there is a XSS vulnerability if a malicious attacker can write into the `xml:base` attribute on an SVG anchor.

AngularJS Cross-site Scripting due to failure to sanitize `xlink.href` attributes
Versions of `angular` prior to 1.5.0-beta.1 are vulnerable to Cross-Site Scripting. The package fails to sanitize `xlink:href` attributes, which may allow attackers to execute arbitrary JavaScript in a victim's browser if the value is user-controlled.


## Recommendation

Upgrade to version 1.5.0-beta.1 or later.

AngularJS improperly sanitizes SVG elements
Improper sanitization of the value of the 'href' and 'xlink:href' attributes in '<image>' SVG elements in AngularJS allows attackers to bypass common image source restrictions. This can lead to a form of  Content Spoofing https://owasp.org/www-community/attacks/Content_Spoofing  and also negatively affect the application's performance and behavior by using too large or slow-to-load images.

This issue affects all versions of AngularJS.

angular vulnerable to regular expression denial of service via the angular.copy() utility
All versions of the package angular are vulnerable to Regular Expression Denial of Service (ReDoS) via the angular.copy() utility function due to the usage of an insecure regular expression. Exploiting this vulnerability is possible by a large carefully-crafted input, which can result in catastrophic backtracking.
