Summary
Passbolt Api E-mail HTML injection
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.
Impact
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
GHSA-V86M-J5F7-CCWH has a CVSS score of 4.4 (Medium). The vector is network-reachable, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.7.0); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is GHSA-V86M-J5F7-CCWH? GHSA-V86M-J5F7-CCWH is a medium-severity cross-site scripting (XSS) vulnerability in passbolt/passbolt_api (composer), affecting versions < 2.7.0. It is fixed in 2.7.0. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- How severe is GHSA-V86M-J5F7-CCWH? GHSA-V86M-J5F7-CCWH has a CVSS score of 4.4 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of passbolt/passbolt_api are affected by GHSA-V86M-J5F7-CCWH? passbolt/passbolt_api (composer) versions < 2.7.0 is affected.
- Is there a fix for GHSA-V86M-J5F7-CCWH? Yes. GHSA-V86M-J5F7-CCWH is fixed in 2.7.0. Upgrade to this version or later.
- Is GHSA-V86M-J5F7-CCWH exploitable, and should I be worried? Whether GHSA-V86M-J5F7-CCWH is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-V86M-J5F7-CCWH is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix GHSA-V86M-J5F7-CCWH? Upgrade
passbolt/passbolt_apito 2.7.0 or later.
