# paicoding: profile text lets logged-in users run scripts for visitors

Link for people: https://infrastack.ai/live/CVE-2026-129141 (this .md is for agents)

paicoding 1.0.0 through 1.0.3 writes user profile text unescaped into an inline JSON-LD script element, so a closing script tag in a profile breaks out of the data. An authenticated user can run scripts in the browsers of people who view their profile and read the non-HttpOnly f-session cookie.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the paicoding version in the deployed project's pom.xml or release tag, `1.0.0` through `1.0.3` are affected.
- Look for the SeoInjectService class and its JSON-LD output on profile pages.

## From the sources

paicoding 1.0.0 through 1.0.3 contains a stored cross-site scripting vulnerability because SeoInjectService embeds user profile text without escaping in an inline JSON-LD script element. Authenticated attackers can add a closing script tag followed by HTML to their profile, executing scripts for visitors of their profile page and stealing the non-HttpOnly f-session cookie.
