Day summary: Today’s RSS activity: 3 item(s) from discourse.ossbase.org, infosec.exchange including “Known Exploited Vulnerability (KEV) Assertion and No Known Exploitable Vulnerability (NKEV) Assessment Format”; “GCVE BCP-05-X-03: Bringing Vulnerability Handling Timelines into Vulnerability Records.Vulnerability records usually provide a good description of what a vulnerability is, which products are affected, how severe it may be, and where additional information can be found.They are often much less effective at describing what happened, when it happened, and who was involved during the vulnerability handling and disclosure process.Following many discussions during VulnOptiCON 2026 in Luxembourg, this limitation became particularly clear. Vulnerability analysts, coordinators, vendors and other participants repeatedly discussed how difficult it can be to reconstruct a reliable timeline during vulnerability analysis and coordinated vulnerability disclosure.To help address this, the GCVE initiative has published a new extension:GCVE BCP-05-X-03 - Vulnerability Handling and Disclosure Timeline.The extension provides a structured and machine-readable way to represent the lifecycle of a vulnerability from discovery and reporting through acknowledgement, validation, remediation and public disclosure. It’s already live in our open-source tool-set.🔗 Blog post https://gcve.eu/2026/10/01/gcve-bcp-05-x-03-bringing-vulnerability-handling-timelines-into-vulnerability-records/🔗 Extension https://gcve.eu/bcp/extension/gcve-bcp-05-x-03/#opensource #openstandard #cve #gcve #cra #cybersecurity #vulnerability”; “GCVE BCP-05-X-03: Vulnerability Handling and Disclosure Timeline”.
