CVE-2025-59941: go-f3 is a Golang implementation of Fast Finality for Filecoin (F3). In versions 0.8.8 and below, go-f3's justification verification caching mechanism has a vulnerability where verification results are cached without properly considering the context of the message. An attacker can bypass justification verification by submitting a valid message with a correct justification and then reusing the same cached justification in contexts where it would normally be invalid. This occurs because the cached verification does not properly validate the relationship between the justification and the specific message context it's being used with. This issue is fixed in version 0.8.9.
The exploitability of CVE-2025-59941 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
This vulnerability, CVE-2025-59941, requires a high level of attack complexity and low privileges, making it difficult but not impossible to exploit. Organizations should ensure robust security configurations to mitigate risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2025-59941, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2025-59941, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
