The European Union's Cyber Resilience Act (CRA) vulnerability reporting requirements take effect on September 11, 2026, imposing strict timelines on software vendors regarding the disclosure of actively exploited flaws. According to industry analysis, vendors may have as little as 24 hours to report vulnerabilities that are actively being exploited in the wild.
The CRA establishes a regulatory framework requiring software providers to maintain detailed records of what components were shipped and when vulnerabilities were discovered. ActiveState, a software supply chain security company, emphasizes that knowing exactly what shipped and when vulnerabilities were identified will be critical for vendors to meet the new reporting obligations.
The reporting requirements apply to software vendors and organizations using platforms like ActiveState's. The 24-hour window applies specifically to flaws that are actively exploited, creating pressure on organizations to implement robust vulnerability detection and tracking processes. Non-compliance could result in regulatory penalties under the EU framework.
The requirements represent a significant shift in vulnerability disclosure practices, moving toward more immediate reporting timelines and greater transparency around software supply chain security. Organizations are advised to evaluate their current vulnerability management processes and ensure they can identify and report actively exploited flaws within the specified timeframe.
