🔒 A critical token validation flaw in Microsoft Entra ID could permit full tenant compromise by abusing undocumented, unsigned actor tokens issued by a legacy Access Control Service. Researcher Dirk-jan Mollema showed that when paired with a vulnerability in the deprecated Azure AD Graph API (CVE-2025-55241) those tokens could impersonate any user — including Global Administrators — across tenants without leaving tenant logs. Microsoft confirmed a fix after the July report and later patched the CVE.

🔓 Radware disclosed ShadowLeak, a zero-click vulnerability in OpenAI's ChatGPT Deep Research agent that can exfiltrate sensitive Gmail inbox data when a single crafted email is present. The technique hides indirect prompt injections in email HTML using tiny fonts, white-on-white text and CSS/layout tricks so a human user is unlikely to notice the commands while the agent reads and follows them. In Radware's proof-of-concept the agent, once granted Gmail integration, parses the hidden instructions and uses browser tools to send extracted data to an external server. OpenAI addressed the issue in early August after a responsible disclosure on June 18, and Radware warned the approach could extend to many other connectors, expanding the attack surface.

⚠ Users of GoAnywhere MFT are urged to install an urgent patch for a critical insecure deserialization vulnerability tracked as CVE-2025-10035, rated CVSS 10. The flaw resides in the License Servlet and can allow an attacker with access to the Admin Console to submit a forged license response that deserializes an arbitrary, actor-controlled object, enabling remote command execution. Fortra released fixes in versions 7.8.4 and 7.6.3 and advises customers not to expose the Admin Console directly to the internet. The issue closely mirrors a 2023 vulnerability that was widely exploited by ransomware groups, elevating the risk of rapid exploitation.

🔍 CISA released a technical analysis of malware used in attacks exploiting two Ivanti Endpoint Manager Mobile (EPMM) vulnerabilities, CVE-2025-4427 and CVE-2025-4428. The agency details two distinct malware sets that used a common web-install.jar loader and malicious listener classes to inject and execute code, exfiltrate data, and maintain persistence. Attackers targeted the /mifs/rs/api/v2/ endpoint via HTTP GET requests with a ?format= parameter, delivering segmented, Base64-encoded payloads. CISA published IOCs, YARA and SIGMA rules and advises immediate patching and treating MDM systems as high-value assets.

🔒 Fortra has released security updates to address a maximum-severity deserialization vulnerability in the License Servlet of GoAnywhere MFT (CVE-2025-10035) that can lead to command injection when a forged license response is accepted. The vendor issued patched builds — GoAnywhere MFT 7.8.4 and Sustain Release 7.6.3 — and advised administrators to remove public access to the Admin Console if immediate patching is not possible. Shadowserver is monitoring over 470 instances, and Fortra emphasized that exploitation is highly dependent on the Admin Console being internet-exposed.

🔒 Fortra has released an urgent patch for GoAnywhere MFT to address a critical deserialization flaw (CVE-2025-10035, CVSS 10.0) in the License Servlet that can allow execution of arbitrary commands when an attacker supplies a forged license response signature. The vendor recommends updating to v7.8.4 or the Sustain Release 7.6.3. If patching cannot be applied immediately, ensure the Admin Console is not publicly accessible. No active exploitation has been reported.

🔒 Researchers disclosed a max-severity vulnerability in Microsoft Entra ID that allowed attackers to request and reuse internal Actor tokens to impersonate any user, including Global Administrators, across tenants. The issue stemmed from a legacy Azure AD Graph API that failed to validate the originating tenant, enabling cross-tenant impersonation without triggering MFA, Conditional Access, or audit logs. Microsoft patched the flaw, tracked as CVE-2025-55241, and rolled a global fix but experts warn that lack of historical visibility leaves uncertainty about past exploitation.

🔒 CISA released details of two malicious toolsets found on an organization's server after attackers chained zero-day vulnerabilities in Ivanti Endpoint Manager Mobile (EPMM). Each set contains a Java loader that installs an HTTP listener to decode, decrypt and execute arbitrary payloads and maintain persistence.
