CVSS Release:
CVE-2025-58451: Cattown is a JavaScript markdown parser. Versions prior to 1.0.2 used regular expressions with inefficient, potentially exponential worst-case complexity. This could cause excessive CPU usage due to excessive backtracking on crafted inputs. In turn, the excessive CPU usage could lead to resource exhaustion, where processing malicious inputs could cause high CPU or memory usage, potentially leading to denial of service. Version 1.0.2 contains a patch. Additionally, users should review and restrict input sources if untrusted inputs are processed.
The exploitability of CVE-2025-58451 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).
No exploitability data is available for CVE-2025-58451.
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-2025-58451, 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-2025-58451, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
