Last updated: 16 Jan 2026, 23:25 UTC
This page consolidates all known Common Vulnerabilities and Exposures (CVEs) associated with wolfssh. 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 wolfssh CVEs: 6
Earliest CVE date: 13 Jul 2022, 16:15 UTC
Latest CVE date: 06 Jan 2026, 18:15 UTC
Latest CVE reference: CVE-2025-15382
30-day Count (Rolling): 2
365-day Count (Rolling): 4
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): 0%
Year Variation (Calendar): 300.0%
Month Growth Rate (30-day Rolling): 0.0%
Year Growth Rate (365-day Rolling): 300.0%
Average CVSS: 1.25
Max CVSS: 7.5
Critical CVEs (≥9): 0
| Range | Count |
|---|---|
| 0.0-3.9 | 5 |

These are the five CVEs with the highest CVSS scores for wolfssh, sorted by severity first and recency.
A heap buffer over-read vulnerability exists in the wolfSSH_CleanPath() function in wolfSSH. An authenticated remote attacker can trigger the issue via crafted SCP path input containing '/./' sequences, resulting in a heap over read by 1 byte.
wolfSSH’s key exchange state machine can be manipulated to leak the client’s password in the clear, trick the client to send a bogus signature, or trick the client into skipping user authentication. This affects client applications with wolfSSH version 1.4.21 and earlier. Users of wolfSSH must update or apply the fix patch and it’s recommended to update credentials used. This fix is also recommended for wolfSSH server applications. While there aren’t any specific attacks on server applications, the same defect is present. Thanks to Aina Toky Rasoamanana of Valeo and Olivier Levillain of Telecom SudParis for the report.
Improper host authentication vulnerability in wolfSSH version 1.4.20 and earlier clients that allows authentication bypass and leaking of clients credentials.
Potential stack buffer overwrite on the SFTP server side when receiving a malicious packet that has a handle size larger than the system handle or file descriptor size, but smaller than max handle size allowed.
A vulnerability was found in wolfSSH's server-side state machine before versions 1.4.17. A malicious client could create channels without first performing user authentication, resulting in unauthorized access.
WolfSSH v1.4.7 was discovered to contain an integer overflow via the function wolfSSH_SFTP_RecvRMDIR.
