LOOK BACK: In 2020, Authlib added two lines letting a JWT header supply the key used to verify that same JWT. A 2022 fix narrowed the condition. In Feb 2026 it was finally deleted. CVE-2026-27962, CVSS 9.1, and six months on nobody has been seen exploiting it.

Full Look Back: three severity scores from one submission, an affected-version range no scanner can read, and why the agreed PR:L predicted the outcome better than the 9.9 did: https://t.co/aTnx9Xh2Aw

LOOK BACK: A CVSS 9.9 RCE on Veeam backup servers, in a product with four ransomware-linked entries in CISA KEV. Six months on, CVE-2026-21666 has no KEV listing, no PoC and no exploitation. The best-documented thing about it turned out to be its paperwork.

The Look Back: how one audit finding became three CVE IDs, why Debian was never affected, and who actually put the 9.8 there: https://t.co/T7aSLAuknX

[CVE Brief @DailyCVEBrief]

LOOK BACK: CVE-2026-3381 shows as 9.8 CRITICAL. The CNA that assigned it supplied no score at all. A Perl module bundles its own copy of zlib, and zlib had a medium-severity infinite loop in a CRC helper. Six months on: no exploitation, not in KEV, EPSS 0.55%.
