Focus on perfree vulnerabilities and metrics.
Last updated: 29 Jun 2025, 22:25 UTC
This page consolidates all known Common Vulnerabilities and Exposures (CVEs) associated with perfree. We track both calendar-based metrics (using fixed periods) and rolling metrics (using gliding windows) to give you a comprehensive view of security trends and risk evolution. Use these insights to assess risk and plan your patching strategy.
For a broader perspective on cybersecurity threats, explore the comprehensive list of CVEs by vendor and product. Stay updated on critical vulnerabilities affecting major software and hardware providers.
Total perfree CVEs: 7
Earliest CVE date: 15 Mar 2023, 03:15 UTC
Latest CVE date: 26 May 2025, 03:15 UTC
Latest CVE reference: CVE-2025-5164
30-day Count (Rolling): 0
365-day Count (Rolling): 3
Calendar-based Variation
Calendar-based Variation compares a fixed calendar period (e.g., this month versus the same month last year), while Rolling Growth Rate uses a continuous window (e.g., last 30 days versus the previous 30 days) to capture trends independent of calendar boundaries.
Month Variation (Calendar): -100.0%
Year Variation (Calendar): 200.0%
Month Growth Rate (30-day Rolling): -100.0%
Year Growth Rate (365-day Rolling): 200.0%
Average CVSS: 0.37
Max CVSS: 2.6
Critical CVEs (≥9): 0
| Range | Count |
|---|---|
| 0.0-3.9 | 7 |
| 4.0-6.9 | 0 |
| 7.0-8.9 | 0 |
| 9.0-10.0 | 0 |
These are the five CVEs with the highest CVSS scores for perfree, sorted by severity first and recency.
A vulnerability has been found in PerfreeBlog 4.0.11 and classified as problematic. This vulnerability affects the function JwtUtil of the component JWT Handler. The manipulation leads to use of hard-coded cryptographic key . The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
