Stored cross-site scripting via unneutralized note fields

Published Oct 26, 2023 · Updated Aug 2, 2024

Stored cross-site scripting in SourceCodester Sticky Notes App 1.0 allows remote attackers to execute script in another user's browser. The add-note.php endpoint accepts crafted noteTitle or noteContent values without sufficient neutralization, allowing stored values to be interpreted as script when displayed. Exploitation requires another user to view the affected note, and the resulting code runs within that user's browser context.
