Passbolt Api E-mail HTML injection
Real-World Exposure
passbolt/passbolt_apiReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for passbolt/passbolt_api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update passbolt/passbolt_api to 2.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v86m-j5f7-ccwh is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-v86m-j5f7-ccwh can be triaged on real exposure rather than presence alone.
Tailored to GHSA-v86m-j5f7-ccwh. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
