TCP Use-After-Free: CVE-2026-98432 / CVSS 9.8

CVE-2026-98432 is a use-after-free in the Linux IPv4 TCP handshake, rated CVSS 3.1 9.8 and reachable by a remote unauthenticated peer on kernels back to 4.4. The post lists fixed stable releases (October 2026) and distribution patch status as of 31 October 2026, plus kernel and MPTCP listener checks. It gives interim nftables and iptables rules that drop IPv4 packets carrying options, and notes Anthropic's claim that Claude wrote a working exploit.

Bunny CDN Security Incident

Bunny CDN status-page notice, posted 28 October 2026, about unauthorized access at an infrastructure provider that hosted one bunny.net CDN node in Armenia. Traffic was stopped within 20 minutes and the server wiped. No access to the node was found, but cached content, Pull Zone configs and TLS certificates could have been exposed, so all platform certificates were reissued. Customers with their own certificates should rotate them with new private keys.

CISA Adds Two Known Exploited Vulnerabilities to Catalog

CISA added two Ivanti Connect Secure vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog on 30 October 2026, citing evidence of active exploitation: CVE-2026-111357 (missing authentication for a critical function) and CVE-2026-118527 (generation of predictable numbers or identifiers). The alert restates BOD 26-04, which requires federal civilian agencies to remediate KEV-listed flaws on exposed assets and check for prior compromise. It also links the KEV nomination form.

Threat Brief: Critical Vulnerabilities in PHP: CVE-2026-109618, CVE-2026-109619 (Updated October 29)

Unit 42 threat brief on PHP2Shell, two PHP remote code execution flaws, CVE-2026-109618 and CVE-2026-109619 (CVSS 4.0 9.2), both caused by longjmp() error handling that leaves memory uninitialized or freed. Cortex Xpanse counted over 22.6 million exposed instances. The 29 October 2026 update says attackers chained PHP2Shell with a Linux kernel privilege escalation against internet-exposed PAN-OS management interfaces. An earlier 23 October claim of post-compromise activity was retracted on 25 October.

CVE-2026-92885 is a critical (CVSS 3.1 9.8, CWE-287) authentication bypass in the Qode Membership WordPress plugin, versions through 2.0.6.2. A misspelled variable in the Facebook token-verification guard skips provider checks, so an unauthenticated attacker with a public nonce can get a session cookie for an existing account, including an administrator. The post gives the fix (2.0.6.3, bundled in Bridge 30.9), KEV/EPSS/SSVC status, and a SOC log-correlation and remediation plan.

CVE-2026-115905 is a ZIP cloaking flaw in the Rust zip crate (zip-rs/zip2), rated CVSS v4.0 10.0 and affecting versions below 9.0.5. ZipArchive reads central-directory metadata while ZipStreamReader reads local headers, so a crafted archive can pass filename inspection and then overwrite a different file during streaming extraction. Version 9.0.5 adds consistency checks, but ZipStreamReader::new leaves them off by default, and extraction is not atomic, so files can be written before an error is raised. The post covers CWE-20 and CWE-436, KEV and EPSS status, Debian status and a six-step investigation trail.
