# PMail: stored XSS in attachments endpoint lets email senders run script

Link for people: https://infrastack.ai/live/CVE-2026-129168 (this .md is for agents)

PMail 2.9.1 through 2.9.8 serves email attachments with the sender-supplied Content-Type, so a crafted HTML attachment linked from a message runs script in the recipient's webmail session. An unauthenticated sender can use this to change passwords, including the administrator's.

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

## Affected

- vendor:PMail affected range not listed fixed no fixed version listed

## How to check

- Check the installed PMail version against the affected range 2.9.1 through 2.9.8

## Timeline

## Documents

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/pmail-2.9.1-through-2.9.8-stored-xss-via-inline-html-attachments

## From the sources

PMail 2.9.1 through 2.9.8 contains a stored cross-site scripting vulnerability because the /attachments/{id}/{cid} endpoint returns email attachments verbatim with the sender-supplied Content-Type after cid: references are rewritten into attachment links. Unauthenticated SMTP senders can email a text/html attachment and a page-covering cid link, so a recipient who clicks the message runs script in their webmail session to change passwords, including the administrator's.
