# PMail: stored cross-site scripting through the send-email API

Link for people: https://infrastack.ai/live/CVE-2026-129169 (this .md is for agents)

PMail versions 2.5.0 through 2.9.8 accept unsanitized HTML sent to /api/email/send, so a logged-in user can store a script in a message. When an administrator opens that message, the script runs in their session and can call privileged APIs such as password changes, enabling account takeover.

_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 `2.5.0` through `2.9.8`.
- Confirm whether untrusted users can authenticate to the PMail instance and call `/api/email/send`.

## From the sources

PMail 2.5.0 through 2.9.8 contains a stored cross-site scripting vulnerability that allows authenticated users to inject scripts by sending unsanitized HTML through /api/email/send. Attackers can embed event-handler payloads like img onerror that execute when administrators view the message, enabling privileged API calls such as password changes for account takeover.
