CVE-2025-46655 describes a Cross-Site Scripting (XSS) bypass vulnerability in CodiMD through version 2.5.4. While CodiMD implements CSP for uploaded SVG documents, this protection can be circumvented when using different-origin file storage like AWS S3, particularly if the AWS architecture lacks components to insert CSP headers. This vulnerability has a CVSS score of 4.9 (MEDIUM), indicating a network-based attack with high complexity, requiring low privileges, and potentially leading to low impact on confidentiality and integrity. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
