# LinkStack: cross-site request forgery in an unknown function up to 4.8.8

LinkStack, a self-hosted link-in-bio web application, has a cross-site request forgery flaw in an unspecified function in versions up to 4.8.8. A remote attacker who tricks a logged-in user into visiting a malicious page could make that user's browser perform actions on the LinkStack site.

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

## How to check

- Check the installed LinkStack version against `4.8.8`; unknown whether later builds are fixed.
- unknown which function is affected; the sources do not name it.

## Fix

- Move to a LinkStack release newer than `4.8.8` once the vendor publishes one; the sources do not name a fixed version.
- unknown whether a configuration change or workaround exists.

## Timeline

## From the sources

A security flaw has been discovered in LinkStackOrg LinkStack up to 4.8.8. The affected element is an unknown function. Performing a manipulation results in cross-site request forgery. Remote exploitation of the attack is possible. The vendor was contacted early about this disclosure but did not respond in any way.
