1. Oracle PeopleSoft Second Pre-Auth RCE — CVE-2026-35278
TL;DR: Oracle’s July 15 CPU patches CVE-2026-35278 (CVSS 9.8), a second pre-auth RCE in PeopleSoft PeopleTools chained with already-exploited CVE-2026-35273. ShinyHunters have compromised 300+ instances across 100+ orgs, predominantly higher education.
What’s New:
- CVE-2026-35278 patches in July 2026 CPU alongside 5 CRITICAL Oracle CVEs (WebLogic CVE-2026-35263 CVSS 9.9, Identity Manager CVE-2026-35268 CVSS 9.9, WebCenter CVE-2026-35270/35280/35281 CVSS 9.1-9.9)
- ShinyHunters chaining CVE-2026-35273 + CVE-2026-35278 for full unauthenticated RCE to data exfil pipeline
- Post-exploitation: MeshCentral C2 via
azurenetfiles[.]net, SSH spray fanout script, HR/payroll/PII theft - Mandiant/GTIG confirmed exploitation May 27–June 9 (zero-day window before June 10 advisory)
- Victim marker file

2. Microsoft Patch Tuesday July 14 — 127 CVEs, Wormable NEGOEX RCE, Kerberos RC4 Enforcement
TL;DR: Today’s Patch Tuesday drops 127 CVEs. Priority-one is CVE-2025-47981 (CVSS 9.8), a wormable heap overflow in SPNEGO NEGOEX reachable via SMB/RDP/HTTP without auth. Kerberos RC4 Phase 2 enforcement also activates today — systems still using RC4 will fail to authenticate.
What’s New:
- CVE-2025-47981 (NEGOEX): wormable, no auth, no interaction, targets SMB 445/RDP 3389/HTTP 80,443 — 2 public PoCs on GitHub
- 127 CVEs total (normalization from June’s 200, still above pre-2026 monthly average)
- Kerberos RC4 hardening Phase 2 enforced today — RC4-only clients/apps will break
- Nightmare Eclipse threatened “bone-shattering” exploit dump on July 14 (not formally canceled)
- GodDamn ransomware (covered July 10) and DragonForce actively exploiting prior month’s CVEs

3. GhostCommit — Prompt Injection via PNG Targets AI Coding Agents
TL;DR: UMKC researchers disclosed GhostCommit (July 11-12), a technique hiding prompt injection inside PNG images referenced from README/AGENTS.md files. Cursor and Antigravity agents exfiltrated .env secrets as integer tuples in code commits. Claude Code refused the injection under all tested models.
What’s New:
- Malicious instructions rendered as text inside PNG, invisible to human reviewers and conventional scanners
AGENTS.mdconvention file instructs coding agent to “derive a build constant” from the image- Exfiltrated secrets encoded as 311-integer tuple embedded in routine-looking code review commits
- Tested successfully against Sonnet, Gemini, GPT-5.5 running in Cursor and Antigravity
- No CVE assigned; technique is model/tool-agnostic

| Splunk ESCU | None | No AI agent activity monitoring rules |
| Elastic | None | No coverage for AI agent credential exfiltration |
| Sigma | None | No rules for AGENTS.md-triggered exfiltration patterns |
