Daniel's Daily Threat Intel & CVE Briefing (from claude)
Tue 15 Jul 2026
Top of the stack: Microsoft's July Patch Tuesday (14 Jul) is the day's priority — a record ~570 Microsoft CVEs with two actively-exploited zero-days, both privilege-escalation bugs in identity infrastructure (AD FS and SharePoint). Patch those two first. In parallel, CISA added a decades-old Cisco IOS CSRF flaw (CVE-2008-4128) to KEV on 13 Jul after confirmed exploitation — audit legacy IOS management planes. Three items are flagged actively-exploited today.
1. CISA KEV / Actively Exploited (lead)
CVE-2008-4128 — Cisco IOS CSRF → arbitrary command execution. Added to KEV 13 Jul 2026; confirmed in-the-wild exploitation of an 18-year-old flaw in the IOS web management interface. So what: internet-exposed or poorly-segmented IOS device web UIs are being abused for command execution — disable the HTTP(S) server or lock it behind ACLs. (SecurityAffairs, SC Media)
CVE-2026-56155 — Microsoft AD FS EoP (CVSS 7.8), actively exploited. Local privilege escalation via insufficient access-control granularity in AD FS (see MS section). (ZDI)
CVE-2026-56164 — Microsoft SharePoint EoP (CVSS 5.3), actively exploited. Missing authentication for a critical function, network-reachable, no user interaction. (BleepingComputer)
Same-week KEV wave (7–10 Jul), all exploited — worth confirming remediation if in scope: Adobe ColdFusion path traversal → RCE (CVE-2026-48282); Langflow auth-bypass/IDOR (CVE-2026-55255) — noted as the first AI-agent platform added to KEV; and Joomla-ecosystem file-upload/access-control bugs (JoomShaper SP Page Builder CVE-2026-48908, Joomlack CVE-2026-56290, Balbooa CVE-2026-56291, iCagenda CVE-2026-48939). (The Hacker News, SecurityWeek)
2. Edge / Network Gear
Quiet in the strict 24–48h window aside from the Cisco IOS KEV item above (CVE-2008-4128) — treat that as the actionable edge item today. No newly-corroborated critical Fortinet/Palo Alto/Citrix/Ivanti/SonicWall advisories published in the last day; the recent SecurityWeek Fortinet/Ivanti critical set (FortiSandbox CVE-2026-25089 CVSS 9.8, Ivanti Sentry CVE-2026-10520 CVSS 10.0) dates to mid-June and should already be in your patch cycle.
3. Microsoft / Windows / Active Directory
Patch Tuesday, 14 Jul 2026 — largest on record. ~570 Microsoft-issued CVEs (≈621 counting all republished/third-party CVEs addressed); 59–63 rated Critical, ~48 of them RCE. (Tenable, ZDI)
CVE-2026-56155 — AD FS EoP (7.8), exploited. Local EoP; high value in federated-identity environments. Patch AD FS servers first.
CVE-2026-56164 — SharePoint EoP (5.3), exploited. Unauthenticated, network-based privilege escalation via missing auth — SharePoint remains under sustained attack (distinct from the CVE-2026-45659 RCE added to KEV on 1 Jul). Patch on-prem SharePoint immediately.
CVE-2026-50661 — BitLocker security-feature bypass, publicly disclosed (not yet exploited). Requires physical access to reach encrypted data — relevant to lost/stolen-device and evil-maid threat models.
So what: two of the three zero-days are identity/domain-compromise primitives — sequence AD FS and SharePoint ahead of the broader 570-CVE backlog.
4. Web / Cloud / DevOps
Adobe ColdFusion CVE-2026-48282 (path traversal → RCE) and Langflow CVE-2026-55255 (auth-bypass IDOR — authenticated users can execute other users' flows) are both actively exploited and in KEV as of this week. If you run ColdFusion or Langflow (LLM/agent app builder), patch now. (http://Threat-Modeling.com)
Adobe's July batch also included a ColdFusion CVSS 9.9 issue (not yet exploited) — standard-priority patch. (ZDI)
No fresh corroborated Kubernetes/critical supply-chain 0-day in the 24h window; ongoing npm/PyPI credential-stealer campaigns continue as background noise.
Watch / developing
Langflow's KEV entry signals attackers are now hunting AI-agent/LLM orchestration platforms as an access vector — inventory any internet-exposed Langflow/agent tooling. Also watch the sheer triage load from the 570-CVE Patch Tuesday: with 48 critical RCEs, expect rapid PoC development over the coming days beyond the three flagged zero-days.
Sign-off: 3 items flagged as actively exploited today (CVE-2026-56155, CVE-2026-56164, CVE-2008-4128), with a cluster of 4–6 additional exploited KEV entries from earlier this week still worth confirming as patched.

Daniel's Daily Threat Intel & CVE Briefing — Fri 7 Aug 2026
Top of the stack: Today is CISA's federal remediation due date for the N-able N-central / Langflow / Tomcat KEV batch — and the N-central bug is the one that matters: CVE-2026-18577, an auth-bypass that is a bypass of the incomplete fix for CVE-2026-18556, is being exploited in the wild since Aug 1 to seize admin on RMM servers and pivot into managed endpoints. If you or clients run N-central, patch to 2026.3.1 Hotfix 1 (2026.3.1.7) and hunt for post-compromise activity before anything else today.
1. CISA KEV / actively exploited (lead)
CVE-2026-18577 — N-able N-central, all versions ≤ 2026.3.1 (pre-Hotfix 1). Unauth auth-bypass → full admin. Exploited in the wild from Aug 1; added to KEV Aug 3. Post-exploit TTPs: abuse of the Take Control feature to reach managed endpoints + Cloudflare Tunnel for persistent backdoor. Fix: 2026.3.1.7. So what: RMM = one box to own the whole estate; treat any unpatched N-central as presumed-compromised.
CVE-2026-18556 — N-able N-central auth-bypass (the incompletely-patched precursor to 18577), CVSS 8.2. KEV, federal due date today.
CVE-2026-9198 — Langflow (open-source AI app-dev platform), CVSS 9.8, unauth code-injection → RCE. Fixed 1.10.1. Repeatedly weaponized in recent months; KEV, due today. So what: internet-exposed AI/LLM tooling is now a routine initial-access target.
CVE-2026-34486 — Apache Tomcat, CVSS 7.5, EncryptInterceptor cluster-messaging bypass. Fixed 11.0.21 / 10.1.54 / 9.0.117. Tied to SNOWLIGHT malware campaign; KEV, due today.
CVE-2026-63077 — JetBrains TeamCity deserialization flaw, added to KEV this week. Verify your CI/CD estate isn't exposing TeamCity to untrusted networks.
2. Edge / network gear
CVE-2026-20316 — Cisco Secure Firewall Management Center (FMC) 7.0–7.7 / 10.0. Static credentials for a low-priv account → unauth remote access to sensitive data; actively exploited as a zero-day (disclosed Jul 30). Base CVSS only 5.3 but Cisco rates SIR High because it's chainable for privilege escalation. So what: not the headline score, but it's live and it's your firewall manager — patch and rotate.
Fortinet/Ivanti criticals (FortiSandbox CVE-2026-25089 9.8; Ivanti Sentry CVE-2026-10520 10.0 / CVE-2026-10523 9.9) are from the June 10 cycle — no new exploitation reported in the last 24–48h; flagged only in case anything remains unpatched.
3. Microsoft / Windows / AD
Quiet in the last 24h. No new in-the-wild Windows/AD/Exchange/Entra items surfaced. August Patch Tuesday lands Aug 11 — July's record 622-flaw cycle (2 zero-days under active attack) should already be deployed; if not, that's your gap.
4. Web / cloud / DevOps
CVE-2026-66066 — Rails Active Storage (< 7.2.3.2, 8.0.x < 8.0.5.1, 8.1.x < 8.1.3.1; 6.x only if configured off-default). Critical; unauth arbitrary file read → potential RCE via libvips ("KindaRails2Shell", pivots on the app master key). Public PoC available (disclosed Aug 1). Mitigation: upgrade Rails/Active Storage, libvips ≥ 8.13, ruby-vips ≥ 2.2.1.
CVE-2026-63030 + CVE-2026-60137 — WordPress core "wp2shell" chain (REST batch-route confusion + author__not_in SQLi). Unauth RCE on default installs 6.9.0–6.9.4 / 7.0.0–7.0.1. Public exploits on GitHub; watchTowr reports in-the-wild exploitation. Fixed 6.9.5 / 7.0.2 (forced auto-update pushed). Slightly older (Jul 18) but still actively exploited — worth a scan sweep.
Watch / developing
Oracle out-of-band Security Alert CVE-2026-35273 surfaced this week — details thin, worth confirming scope. Senserva notes ~30 KEV entries this month with 2 tied to ransomware campaigns (Microsoft/Fortinet/Cisco most-affected) — watch for ransomware operators folding the N-central and Langflow bugs into their access-broker playbooks.
Sign-off: 7 items flagged actively exploited today (N-central ×2, Langflow, Tomcat, TeamCity, Cisco FMC, WordPress wp2shell); the single must-do is patching N-central before CISA's due date closes.

One caveat worth noting for your own verification: NVD detail pages were unreachable during this run, so severities above are corroborated against vendor advisories, CISA, and reputable trackers rather than NVD directly — the Langflow 9.8 and Cisco 5.3 figures each have two independent sources, but confirm against NVD before citing formally.
Post summary
The briefing highlights several high‑impact CVEs that have already been exploited in the wild, outlines the available patches and mitigations, and urges immediate remediation to prevent further compromise.
🚨 On 6/9/26, #Ivanti published a security advisory for 2 critical vulns affecting Ivanti Sentry (FKA MobileIron Sentry).

Read on: https://r-7.co/4arpQHd https://t.co/F4mG85Vk5u
Post summary
Ivanti disclosed two critical vulnerabilities in its Sentry product—a command‑injection flaw with CVSS 10.0 and an authentication bypass flaw with CVSS 9.9. No patch or exploit information is mentioned in the tweet.
🔼 Analysis of the vulnerability chain CVE-2026-10520 and CVE-2026-10523 in Ivanti Sentry
PT ID: PT-2026-47806
The research describes two critical vulnerabilities in Ivanti Sentry: CVE-2026-10520 and CVE-2026-10523 -> (https://dbugs.ptsecurity.com/vulnerability/CVE-2026-10523). The first is an OS command injection vulnerability (CWE-78): improper input handling in an API allows arbitrary commands to be executed at the operating system level without authentication. The second is an authentication bypass vulnerability (CWE-288), which allows a remote attacker to bypass authentication mechanisms and create arbitrary administrative accounts with full system access.
The combination of these vulnerabilities enables a full pre-auth compromise chain: an attacker can first bypass authentication to gain administrative access, and then leverage command injection to execute code with root privileges. This can lead to complete control over the gateway, compromise of credentials and session tokens, and also opens the path for further lateral movement within the infrastructure.
