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.

PHP2Shell: From the attacker’s perspective

PHP2Shell is the public exploit for CVE-2026-109618 (corrupted internal state at the memory limit, allowing hijack during cleanup) and CVE-2026-109619 (double free used to leak memory and defeat ASLR). Orca ran the GitHub tool unchanged against an unpatched PHP server and got command execution. It then built its own exploit with AI from the patch, which worked on PHP 8.4.26 and WordPress. Fixed in 8.2.35, 8.3.36, 8.4.27 and 8.5.12.

Critical PHP “PHP2Shell” RCE Vulnerabilities Allow Unauthenticated Remote Code Execution (CVSS 9.2)

PHP2Shell is the informal name for CVE-2026-109618 and CVE-2026-109619 (CVSS v4.0 9.2), unauthenticated remote code execution flaws in the PHP core runtime. Patches for branches 8.2 to 8.5 were scheduled for 21 October at 14:00 UTC, while PHP 8.1 and older get no fix; about 884,000 internet-facing hosts run those versions. watchTowr reproduced CVE-2026-109618, no public PoC existed at writing, and Sansec expects mass exploitation within 15 minutes of release.

Frontier-Level Red-Teaming From a Self-Hostable Open-Weight Model: Testing NVIDIA Nemotron 3.5 Super

Orca Security's research team built an internal prototype, Agent Piercer, that attacks AI agents by choosing probes, writing attacks and judging whether they worked. They compared NVIDIA Nemotron 3.5 Super (self-hosted on 4×L40S via SageMaker) with Opus 4.8, GPT-6 Astra and Grok 4.7 as the driving model against the same live target. Nemotron matched the frontier models on vulnerability types found (four) and was the only one to complete every simple test and judge all 57 real attack conversations. The post also notes that some proprietary models declined authorized red-team tasks under default safety settings, which makes self-hosted open-weight models attractive for offensive testing.

Critical GitLab RCE Lets Unauthenticated Attackers Execute Code on Servers (CVE-2026-97229)

Orca Security analysis of CVE-2026-97229, a CVSS 10.0 flaw in GitLab CE/EE. An integer overflow (CWE-190) in the CI/CD regular expression compiler gives memory corruption and code execution as the git user. It is triggered by a crafted regex in .gitlab-ci.yml combined with a UTF-8 repository path, with no authentication needed on instances that allow public project creation or self-registration. Lists affected branches (19.2 before 19.2.8, 19.3 before 19.3.5, 19.4 before 19.4.2), the absence of a workaround, interim mitigations, and a Rapid7 PoC against GitLab CE 19.4.1 with ASLR on. Notes a prior max-severity GitLab bug (CVE-2026-85706) was probed in the wild within hours and later added to CISA KEV.

Malicious npm Campaign “MALFEX” Delivers RAT and Stealer via Eight Packages with 40,000+ Downloads

Orca Security details "MALFEX," a supply-chain campaign active since August 2023 in which a suspected lone Brazilian threat actor published eight malicious npm packages (tlxbnhd, tldriver, mxdriver, img-to-native, native-runner, function-flag, function-color, cdn-img-fetch) that together drew over 40,767 downloads. Using postinstall lifecycle hooks, the packages deliver three malware families to Windows hosts: the Go-based Overlord RAT (with a Solana blockchain C2 resolver), the Node.js "movinlike" credential/Discord/crypto-wallet stealer, and rotating downloader payloads — with three packages (notably function-flag) still live on npm and only six of the eight carrying OSV advisories at publication time. The piece includes host IOCs (file paths, scheduled task name), affected package lists, and remediation steps (lockfile auditing, credential rotation) alongside a pitch for Orca's SCA detection of the OSV-flagged packages.

Critical Atlassian Path Traversal Exposes Sensitive Files Across 8 Products

Orca Security details CVE-2026-21589 (CVSS 9.3), a critical unauthenticated path traversal flaw affecting all versions of eight Atlassian Data Center and Server products: Bitbucket, Confluence, Jira Software, Jira Service Management, Bamboo, Crowd, Crucible, and Fisheye. Insufficient path validation lets remote attackers read arbitrary files within the web application root without authentication, and in Crowd SSO deployments this can expose plaintext credentials usable to create administrative accounts and take over the entire Atlassian ecosystem. The advisory lists fixed versions for each product and recommends WAF rules and log review for organizations unable to patch immediately.

Citrix NetScaler Zero-Day Exploited in the Wild Crashes SAML Authentication Services

Analysis of CVE-2026-88779 (CVSS v4.0 8.7), an unauthenticated memory-overflow flaw in the nsaaad SAML authentication handler on Citrix NetScaler ADC/Gateway that lets attackers crash the SAML service and lock out VPN/SSO access indefinitely through repeated triggering. Affects NetScaler 14.1 before 14.1-73.41 and 13.1 before 13.1-64.28 (plus FIPS/NDcPP builds); watchTowr Labs reproduced it via honeypot activity, Citrix confirmed targeted in-the-wild exploitation from IP 213.209.159.55, and CISA added it to KEV on 2026-10-04 with an Oct 7 federal remediation deadline. Some researchers suspect the overflow could extend to RCE beyond the documented DoS, though Citrix hasn't confirmed this.

Connect Orca’s ChatGPT Plugin: Cloud Risk Context in Chat and Codex

Orca Security's plugin connects ChatGPT and Codex to Orca's MCP server, letting security teams and developers query cloud alerts, attack paths, effective IAM permissions, and code-to-cloud origins directly from chat or a coding agent instead of logging into a console. The post walks through six security-team use cases (exposure discovery, CVE impact triage, alert-to-blast-radius investigation, identity permission review, CISO reporting) and three developer workflows in Codex where alerts are traced back to the Terraform/code that created the misconfiguration and fixed in place.

WordPress “Comment2Shell” XSS-to-RCE Chain Lets Unauthenticated Attackers Compromise Servers via Malicious Comments

CVE-2026-93485 (CVSS 7.1) is a stored XSS-to-RCE chain in WordPress Core's wpautop() function (wp-includes/formatting.php), where a mismatch between comment sanitization at save time and HTML reformatting at display time lets an unauthenticated attacker inject live event handlers via a crafted comment. When a logged-in administrator views the page, the script executes and installs a malicious plugin containing a web shell, achieving full RCE. It affects WordPress Core 4.7 through 7.1.0 (essentially all installs, including block themes since Twenty Twenty-Two), and is fixed in 7.1.1 with backports down to 4.7.36; no public PoC or in-the-wild exploitation was reported at disclosure time.

npm Supply-Chain Attack Abuses Trusted Publishing to Ship GHAPPIER Loader

Orca Security details a supply-chain attack on the npm package @dforge-core/dforge-mcp, where a compromised maintainer account modified the GitHub Actions release workflow so any push to main triggered an OIDC-based trusted publish, shipping malicious version 0.2.21 with valid Sigstore provenance. The four-stage GHAPPIER loader activated only when the MCP server launched, deployed a self-deleting remote shell, and per CloudSEK's tracing appeared across 65 repos and 22 accounts; a second payload matched PolinRider, a DPRK-linked campaign using Ethereum transactions for C2. The piece underscores that npm provenance attests build origin, not source integrity, and lists remediation steps since no CVE or advisory yet exists.

Incident Automation: Benefits, Tools & Best Practices

Orca Security guide distinguishing alerts, incident records, and actions in incident response automation, mapping a cloud storage-bucket-exposure incident through detection, declaration, enrichment, routing/paging, and suppression steps. Draws on AWS Well-Architected event/incident/problem management guidance, ISO/IEC 27035-3:2020 lifecycle, CISA containment guidance, and Azure alert processing rules to argue automation should be introduced step-by-step based on reversibility rather than as one switch.

Critical Elementor Pro File Upload Flaw Enables Unauthenticated Remote Code Execution on WordPress Sites

CVE-2026-32475 (CVSS 9.0) is an unauthenticated arbitrary file upload leading to RCE in Elementor Pro's Forms module (versions up to 4.2.1), caused by the extension-blocklist check and the file-move step running in two separate loops with different empty-file handling, letting a two-part file submission bypass the blocklist and drop a PHP webshell into the public wp-content/uploads/elementor/forms/ directory. The post also flags related WordPress core CVE-2026-65640 (CVSS 8.8, fixed in 7.0.4), an Author-level RCE via malicious PostScript upload requiring Imagick and Ghostscript. Fix: upgrade Elementor Pro to 4.2.2+ and WordPress core to 7.0.4, and audit the uploads/elementor/forms directory for planted PHP files.
