Reachability analysis for vulnerability triage
Only 10-30% of SCA findings are ever actually invoked by your code. Reachability analysis finds which ones, cutting patch backlogs without hiding real risk.
Vulnerability fatigue and the case for risk-based prioritization
48,185 CVEs were published in 2025 alone. Most teams can't triage that volume — reachability and exploit maturity data show which ones actually matter.
CVE-2025-29927: inside the Next.js middleware auth bypass
A single spoofed header let attackers skip Next.js middleware entirely — CVSS 9.1, four major versions affected, exploited in the wild within days.
SBOM-based blast radius analysis for vulnerable dependencies
An SBOM tells you what's inside one artifact. It takes a dependency graph across every service to know what breaks first when a library gets a CVE.
A prioritization framework for triaging security alerts at scale
Only 2.6% of CVEs tracked in 2019 saw real-world exploitation, per Kenna Security/Cyentia — yet most teams still triage by CVSS alone. Here's a better framework.
Continuous vulnerability management: the discovery-to-verification lifecycle
CISA's new BOD 26-04 gives federal agencies as little as 3 days to remediate the highest-risk flaws — a preview of the SLA pressure every engineering org now faces.
Inside CVE-2023-46233: How crypto-js Shipped a 1.3-Million-Times-Weaker Key Derivation
crypto-js versions before 4.2.0 defaulted PBKDF2 to SHA1 with a single iteration — NVD calls it 1,300,000 times weaker than modern standards. Here's the fix.
The CUPS RCE Chain: A Technical Breakdown of CVE-2024-47176
Four medium-severity CUPS bugs chained into unauthenticated RCE on UDP/631 — a masterclass in why CVSS scores per-CVE miss the real risk of a vulnerability chain.
Inside CVE-2023-38545: the libcurl SOCKS5 heap overflow
A single off-by-length check in curl's SOCKS5 handshake, live for over three years across libcurl 7.69.0–8.3.x, earned a 9.8 CVSS score and a CWE-787 out-of-bounds write.
CVSS 4.0 vs. 3.1: what actually changed, and why your priority list should too
CVSS 4.0 killed the Scope metric, added Attack Requirements, and split scoring into CVSS-B/BT/BE/BTE labels — here's what that means for triage.
Exploitability vs. breakability: a practical rubric for vulnerability triage
CVSS says a flaw could be bad. CISA's KEV catalog, now past 1,300 entries, says one actually was exploited. Most teams still triage as if the two are the same.
HTTP/2 CONTINUATION Flood: Inside CVE-2024-27316 and the Frame-Based DoS Class
A single TCP connection with no END_HEADERS flag was enough to crash major HTTP/2 servers — worse than Rapid Reset, and it took the industry a decade to check for it.
