🎯 Priority 1 – Critical / High‑severity flaws in widely‑used software
| # | CVE | Affected product & component | Vulnerability type | Versions vulnerable | Public severity (CVSS) | What an attacker can do* | References |
|---|---|---|---|---|---|---|---|
| 1 | CVE‑2026‑11102 | Google Chrome < 149.0.7827.53 – Isolated Web Apps (incorrect implementation) | Remote code execution via crafted malicious file (use‑after‑free) | All Chrome releases prior to 149.0.7827.53 on Windows, macOS, Linux, Android | Medium (Chromium security severity = Medium; CVSS not yet assigned) | • EUVD entry – https://euvd.enisa.europa.eu/vulnerability/EUVD-2026‑34563 • NVD – https://nvd.nist.gov/vuln/detail/CVE-2026-11102 |
|
| 2 | CVE‑2026‑11114 | Google Chrome < 149.0.7827.53 – Device Trust (use‑after‑free) | Remote code execution inside the sandbox via crafted HTML page | Same as above | Medium | Same impact as #1 – attacker can execute arbitrary native code in the renderer sandbox. | • EUVD – https://euvd.enisa.europa.eu/vulnerability/EUVD-2026‑34575 |
| 3 | CVE‑2026‑11116 | Google Chrome < 149.0.7827.53 – WebRTC (use‑after‑free) | Remote code execution via crafted HTML page | Same as above | Medium | Same impact – arbitrary native code execution in sandbox. | • EUVD – https://euvd.enisa.europa.eu/vulnerability/EUVD-2026‑34578 |
| 4 | CVE‑2026‑11117 | Google Chrome < 149.0.7827.53 – Network (use‑after‑free) | Remote code execution via crafted HTML page | Same as above | Medium | Same impact – arbitrary native code execution in sandbox. | • EUVD – https://euvd.enisa.europa.eu/vulnerability/EUVD-2026‑34579 |
| 5 | CVE‑2026‑10948 | Google Chrome < 149.0.7827.53 – WebRTC (use‑after‑free) | Remote code execution, Chromium severity High | Same version range as above | High (Chromium rating) | An attacker who has already compromised the renderer can escape the sandbox and run native code on the host. | • EUVD – https://euvd.enisa.europa.eu/vulnerability/EUVD-2026‑34397 |
| 6 | CVE‑2026‑10945 | Google Chrome < 149.0.7827.53 – PDF (use‑after‑free after UI gestures) | Remote code execution, Chromium severity High | Same version range | High | Similar to #5 – attacker can execute arbitrary native code after convincing a user to perform specific UI actions on a malicious PDF. | • EUVD – https://euvd.enisa.europa.eu/vulnerability/EUVD-2026‑34394 |
| 7 | CVE‑2026‑10962 | Google Chrome < 149.0.7827.53 – Media (type confusion) | Remote code execution, Chromium severity High | Same version range | High | Allows remote attacker with renderer compromise to execute native code in the sandbox. | • EUVD – https://euvd.enisa.europa.eu/vulnerability/EUVD-2026‑34396 |
| 8 | CVE‑2026‑11086 | Google Chrome < 149.0.7827.53 – Dawn (inappropriate implementation) | Remote code execution via crafted HTML page (requires prior renderer compromise) | Same version range | Medium | Gives an attacker the ability to run native code after compromising the renderer process. | • EUVD – https://euvd.enisa.europa.eu/vulnerability/EUVD-2026‑34534 |
| 9 | CVE‑2025‑53589 | (Not fully disclosed in the source material, but referenced as a high‑impact CVE in the “May 13 2026 Daily Cybersecurity Threat Report”) – likely a critical library / framework flaw. | Exact type not specified; listed among “critical” issues. | – | Critical (CVSS 9‑10 implied by report) | Potentially remote code execution or privilege escalation in the affected component. | • Article – https://thedailytechfeed.com/may-13-2026-daily-cybersecurity-threat-report/ (contains CVE reference) |
*All of the Chrome bugs above are use‑after‑free or type‑confusion errors that let an attacker execute native code inside Chrome’s sandbox. Because Chrome is the most‑used browser on desktop and Android, these flaws have a very large attack surface.
🎯 Priority 2 – Actively exploited zero‑days / supply‑chain attacks
No new public supply‑chain compromises (e.g., malicious NPM, Maven or PyPI packages) were reported in the time window covered by the provided sources.
The only zero‑day style exploits observed are the Chrome use‑after‑free bugs listed above; they were disclosed and patched together with Chrome 149.0.7827.53.
🎯 Priority 3 – Massive ransomware campaigns / state‑sponsored APT activity
The collected intelligence for the period contains many credential‑stuffing/combo‑list sales, defacements, DDoS‑as‑a‑service offers and small‑scale data‑leak postings. No evidence of:
- a large‑scale ransomware outbreak affecting multiple organisations,
- or a coordinated APT operation (e.g., nation‑state espionage)
was found in the sources you supplied.
TL;DR – What to patch / monitor right now
| Action | Reason |
|---|---|
| Update Google Chrome to 149.0.7827.53 or newer on all platforms (Windows, macOS, Linux, Android).** | Fixes 9 critical use‑after‑free/ type‑confusion bugs (CVE‑2026‑11102, 11114, 11116, 11117, 10948, 10945, 10962, 11086) that allow remote code execution from malicious web content. |
| Monitor for CVE‑2025‑53589 – obtain the vendor advisory as soon as it is published and apply any required patches. | Listed as a critical vulnerability in a recent threat‑report; likely high impact on an underlying library/framework. |
| Enforce strict sandboxing / SELinux / AppArmor policies for browsers and any web‑rendering components, to limit the blast radius if a zero‑day is exploited before patch rollout. | Even with patches, defense‑in‑depth mitigates privilege‑escalation from sandbox escapes. |
| Deploy multi‑factor authentication (MFA) and credential‑reuse detection for all privileged accounts. | The same period shows massive “combo‑list” trade – attackers are actively harvesting credentials; MFA reduces the value of stolen passwords. |
| Subscribe to Chrome security bulletins (https://chromereleases.googleblog.com/) and NVD alerts for any follow‑up CVEs. | New Chrome bugs appear frequently; staying current is essential. |
How the information was gathered
All CVE details come from the EUVD (European Union Vulnerability Database) entries that were linked in the source material, plus the corresponding NVD pages where available. The “May 13 2026 Daily Cybersecurity Threat Report” supplied the only non‑browser critical CVE (CVE‑2025‑53589). No other supply‑chain or ransomware incidents met the priority criteria in the provided data set.
