wolfSSL — Vulnerabilities & Security Advisories 61

All 61 CVE vulnerabilities found in wolfSSL, with AI-generated Chinese analysis, references, and POCs.

This page aggregates known weaknesses and vulnerability disclosures associated with the wolfSSL cryptographic library product maintained by wolfSSL Inc. It serves as a centralized resource for tracking security issues specific to this embedded SSL/TLS implementation, covering common weakness enumerations (CWE) relevant to its codebase and deployment configurations. The content compiles publicly available security advisories, bug reports, and vulnerability details released by the vendor and third-party researchers over the past several years. This historical timeline includes updates from major releases such as the 4.x, 5.x, and 6.x series, ensuring coverage of both legacy and current support streams. Visitors can use this aggregation to monitor the security posture of wolfSSL by reviewing how specific vulnerability classes have been addressed over time. Users may also investigate individual component weaknesses to understand the root causes and mitigation strategies applied by the development team. The data facilitates deeper analysis of recurring patterns, such as buffer overflows or memory management errors, within the library’s core functions. By centralizing these records, the page supports security analysts, developers, and auditors in assessing risk, verifying patch status, and conducting compliance reviews. It does not provide real-time threat intelligence or private exploit details but focuses on documented, resolved, or acknowledged security flaws. This structured overview aids in evaluating the long-term maintenance practices and responsiveness of the wolfSSL project to emerging threats in the cryptographic ecosystem.
