CVE-2020-26239 is a DOM-based Cross-Site Scripting (XSS) vulnerability affecting Scratch Addons versions prior to 1.3.2. Specifically, the "More Links" addon within the Scratch Addons WebExtension for Chrome and Firefox incorrectly unescaped HTML-escaped values, allowing for XSS if a user visited a specially crafted website. Rated Medium (CVSS 5.4), this vulnerability requires user interaction (UI:R) and a low privilege level (PR:L) to exploit, potentially leading to limited impact on confidentiality and integrity. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
