Passbolt Api E-mail HTML injection

GHSA-v86m-j5f7-ccwh

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (passbolt/passbolt_api 2.7.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Passbolt sends e-mail to users to warn them about different type of events such as the creation, modification or deletion of a password. Those e-mails may contain user-specified input, such as a password’s title or description. Passbolt does not escape the user’s input properly, resulting in the user being able to inject HTML code in an e-mail. An authenticated attacker could share a password containing an img HTML tag in its description with an other user to obtain information about their mail user-agent. This vulnerability has a very low impact. Most MUA do not embed remote images to protect their users’ privacy.

# Patch Next advisory brief: GHSA-v86m-j5f7-ccwh

Advisory: Passbolt Api E-mail HTML injection
IDs: GHSA-v86m-j5f7-ccwh
Record: https://patchnext.com/advisories/ghsa-v86m-j5f7-ccwh (revision 1, source checked 26 Oct 2026, 14:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: passbolt/passbolt_api 2.7.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist passbolt/passbolt_api: affected < 2.7.0; fixed in 2.7.0

## Suggested inspection (read-only)
- Packagist passbolt/passbolt_api: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on passbolt/passbolt_api.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-v86m-j5f7-ccwh (GitHub-reviewed advisory GHSA-v86m-j5f7-ccwh lists affected ranges: Packagist passbolt/passbolt_api >=0 <2.7.0)

Commands are suggestions: review each one before running it.
