Summary
Passbolt Api Tabnabbing when opening URI with menu "Open URI in a new tab"
Description
A user could create and share a resource with a malicious URI. When the victim opens with menu “Open URI in a new tab” function, the malicious page has access to the window.opener object.
Impact of issue
The newly opened malicious page can for example change the window.opener.location to redirect the user to a phishing page, or call a JavaScript function served by the AppJS on the user behalf for example to try to affect the integrity of the data.
Impact
GHSA-QM5V-PJ64-852J has a CVSS score of 5.5 (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 (2.11.0); 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-QM5V-PJ64-852J? GHSA-QM5V-PJ64-852J is a medium-severity security vulnerability in passbolt/passbolt_api (composer), affecting versions < 2.11.0. It is fixed in 2.11.0.
- How severe is GHSA-QM5V-PJ64-852J? GHSA-QM5V-PJ64-852J has a CVSS score of 5.5 (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-QM5V-PJ64-852J? passbolt/passbolt_api (composer) versions < 2.11.0 is affected.
- Is there a fix for GHSA-QM5V-PJ64-852J? Yes. GHSA-QM5V-PJ64-852J is fixed in 2.11.0. Upgrade to this version or later.
- Is GHSA-QM5V-PJ64-852J exploitable, and should I be worried? Whether GHSA-QM5V-PJ64-852J 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-QM5V-PJ64-852J 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-QM5V-PJ64-852J? Upgrade
passbolt/passbolt_apito 2.11.0 or later.
