CVE-2021-45105: the Log4j denial-of-service flaw recursion built
CVE-2021-45105 scored CVSS 5.9 and let a single crafted lookup string crash a JVM with a StackOverflowError — no RCE required, just uncontrolled recursion.
Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
CVE-2021-45105 scored CVSS 5.9 and let a single crafted lookup string crash a JVM with a StackOverflowError — no RCE required, just uncontrolled recursion.
Only 2-6% of published CVEs are ever exploited in the wild, yet a much larger share carry CVSS 7.0+ scores — a gap that quietly wrecks patch prioritization.
A CVSS 9.8 flaw let a single internal forward skip Spring Security's URL-based access checks entirely — here's the root cause and the exact config fix.
CVSS 9.8. Apache Commons Text 1.5–1.9 ran attacker strings through a script interpolator by default — here's the root cause and the fix.
OpenSSL pre-announced a 'critical' flaw in October 2022. It shipped as HIGH severity. Here's the buffer overflow, the downgrade, and the safe patch path.
A crafted vendor.json field let attackers run shell commands from inside a security scanner — CVE-2022-40764 shows why CLI tools must never build shell strings.
A CVSS 9.8 flaw in Apache Commons Configuration 2.4–2.7 let default interpolators run script-engine expressions from untrusted config strings.
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.
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.
