jedisct1 · x · 2026-11-11

VulnCheck's seven-month tracking of Anthropic's Project Glasswing reveals a widening gap between vulnerability discovery and remediation: 37,966 reported findings produced 442 CVEs (0.5% of all CVEs this year, only 2 exploited in the wild), with just 217 marked fixed. Since September, 12,000 new findings added but only 15 additional fixes. Some 1,654 findings (4.4%) marked duplicates—nearly 8x the number fixed—and 419 withdrawn, raising questions about Anthropic's claimed true-positive rate rising from 90.8% to 94.2%. Its OSS Scanner shifts validation onto maintainers: curl rejected 19 of 34 published reports, confirmed 6 as low severity, with 9 still pending.
