CVE-2026-50883 Details
Description
An HTML injection vulnerability in the /src/highlight.rs component of matze wastebin v3.4.1 allows attackers to execute arbitrary scripts via a crafted payload.
A vulnerability allowing HTML injection has been identified in Matze Wastebin version 3.4.1, specifically within the highlight component. This issue arises because the application returns unescaped long lines from the syntax highlighting fallback, allowing attackers to execute arbitrary scripts by injecting crafted payloads. When a line exceeds 2048 characters, any HTML metacharacters can be transferred from the paste text into the rendered DOM as raw HTML, bypassing normal escaping procedures.
