CVE-2024-23745
CWE-77Published: January 31, 2024· Updated: Jun 17, 2026
Official Description
In Notion Web Clipper 1.0.3(7), a .nib file is susceptible to the Dirty NIB attack. NIB files can be manipulated to execute arbitrary commands. Additionally, even if a NIB file is modified within an application, Gatekeeper may still permit the execution of the application, enabling the execution of arbitrary commands within the application's context. NOTE: the vendor's perspective is that this is simply an instance of CVE-2022-48505, cannot properly be categorized as a product-level vulnerability, and cannot have a product-level fix because it is about incorrect caching of file signatures on macOS.
Risk Analysis
Notion Web Clipper 1.0.3(7) is susceptible to a Dirty NIB attack, where manipulated NIB files can lead to arbitrary command execution. This critical flaw bypasses macOS Gatekeeper protections.
No public exploit is known, and it is not in KEV. The vulnerability is remotely exploitable with low complexity.
The vendor notes this is an issue with macOS signature caching; users should ensure their system is fully patched and avoid installing untrusted extensions.
Technical Analysis
CVE-2024-23745 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
