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 An earlier 23 October claim of post-compromise activity was retracted on 25 October.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-2026-98432: 9.8 CVE affecting all Ubuntu versions

CVE-2026-98432 is a Linux kernel use-after-free in the IPv4 TCP stack, tracked by Ubuntu (published 15 October 2026, updated 29 October 2026). ireq_opt/inet_opt were freed with plain kfree() while another CPU built a SYNACK under RCU, so ip_options_build() read freed memory; the fix uses kfree_rcu(). Ubuntu rates it High priority, CVSS v3.1 9.8 and v4.0 8.3. The page text does not list per-release package status.

CVE-2026-101767: Critical Oracle EBS SQL Injection Actively Probed in the Wild

CVE-2026-101767 is a CVSS 9.8 unauthenticated SQL injection in Oracle E-Business Suite's Application Object Library, reachable through the /OA_HTML/AppsTCFServer servlet (GanttDataServer) and chainable to OS command execution. It affects versions 12.2.3 to 12.2.15 and was fixed in the October 2026 Critical Patch Update. Horizon3.ai found it, and Defused saw probing on honeypots on 27 October 2026. Interim mitigation is removing the servlet from the URL firewall allowlist.

CVE-2026-20362 | Cisco Finesse Server-Side Request Forgery Vulnerability

CVE-2026-20362 is an unauthenticated server-side request forgery in Cisco Finesse (CVSS 3.1 score 7.2), found by Horizon3 researchers Noah King and Brandon Peterson. The embedded Apache Shindig content proxy fetches attacker-supplied URLs, including loopback services such as the Finesse REST API at 127.0.0.1:8082, which returns SystemInfo with node hostnames and the XMPP domain. Cisco published its advisory on 7 October 2026. Fixes are planned for January and February 2027, and no workaround exists.

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.

CVE-2026-106173 is a critical (CVSS 9.4) unauthenticated arbitrary file write in FortiSIEM's phQueryMaster gRPC service on port 27918/TCP. The SendQueryResult method builds a path from the query-id parameter without validation, so "../" sequences escape the directory and a null byte drops the appended filename and extension. Overwriting /opt/charting/redishb.sh, which runs every 60 seconds, gives remote command execution. Horizon3.ai published the analysis and a PoC.

Python2Shell is the Python-side impact of CVE-2026-111497 (Node2Shell), a Brotli decoder flaw (CVSS 4.0 9.2) in DecodeBlockTypeAndLength() that mixes an unchecked return value with an out-of-bounds write. Brotli 1.2.0 and earlier, and brotlicffi 1.2.0.x, are affected through urllib3, requests, httpx, aiohttp and Scrapy. Fixes are Brotli 1.2.1 and brotlicffi 1.2.1.0; as of 23 October 2026 advisory databases do not map the CVE to either package. The post lists checks and workarounds.
