A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

The vendor indicates no product-level fix is available since the issue stems from macOS's file signature caching. Users should ensure their macOS systems are updated with the latest security patches from Apple to address the underlying OS-level issue. No specific mitigation actions are provided by the vendor for Notion Web Clipper itself.

Description

Notion Web Clipper 1.0.3(7) includes a .nib file vulnerable to the Dirty NIB attack, allowing manipulation to execute arbitrary commands. Gatekeeper on macOS may still allow execution of the application even if the NIB file is modified, enabling command execution within the app's context. The vendor considers this issue a manifestation of CVE-2022-48505 related to macOS file signature caching, not a product-level vulnerability, and states no product-level fix is applicable.

Impact

An attacker able to manipulate the .nib file could execute arbitrary commands within the context of the Notion Web Clipper application. However, this is contingent on macOS Gatekeeper's incorrect caching behavior, which may allow execution despite file modifications. The vendor does not consider this a product-level vulnerability, implying limited direct impact on Notion's security posture beyond the underlying OS issue.

Summary

The vulnerability in Notion Web Clipper 1.0.3(7) involves a .nib file susceptible to the Dirty NIB attack, where manipulated NIB files can execute arbitrary commands. Despite modifications, macOS Gatekeeper may permit the application to run due to incorrect caching of file signatures. The vendor classifies this as an instance of CVE-2022-48505, attributing the root cause to macOS's handling of file signatures rather than a flaw in the Notion product itself, and thus no direct product fix is available.
