Dom Sanitizer
Monthly
DOMSanitizer before version 1.0.10 fails to sanitize CSS content within SVG <style> elements, allowing attackers to inject url() references and @import rules that trigger unauthorized HTTP requests to attacker-controlled hosts when the sanitized SVG is rendered in a browser. This affects PHP applications using the vulnerable library to sanitize user-supplied SVG content, enabling information disclosure through request metadata and potential CSRF attacks. The vulnerability requires user interaction (rendering the SVG) but affects all downstream users of the sanitized content due to scope change (C:L, S:C).
DOMSanitizer (aka dom-sanitizer) before 1.0.7 allows XSS via an SVG document because of mishandling of comments and greedy regular expressions. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
