Stored XSS via unneutralized article metadata
Published Apr 27, 2023 · Updated Jan 31, 2025
Stored XSS in Emlog Pro 2.0.3 allows remote authenticated users to execute arbitrary scripts through crafted article metadata. The article editor stores crafted Title or Summary values without effective output neutralization, then renders the payload as executable markup. Authenticated article-editing access and a visitor loading the affected content are required, exposing the visitor's browser context to attacker-supplied script.
