CVE-2026-60977 is a critical, easily exploitable vulnerability in Oracle WebLogic Server that allows an unauthenticated attacker with network access via RMI to fully compromise the server. With a CVSS score of 9.8, successful exploitation can lead to complete takeover of confidentiality, integrity, and availability. Organizations running affected WebLogic versions should prioritize immediate patching due to the low attack complexity and lack of authentication requirements.

A critical use-after-free vulnerability in the DOM Core & HTML component of Firefox and Thunderbird could allow attackers to execute arbitrary code via crafted web content. The flaw has been patched in Firefox 154, Firefox ESR 140.14/153.1, and Thunderbird 154, 140.14, and 153.1. With a CVSS score of 9.8, unpatched systems are at severe risk of remote exploitation.

A critical use-after-free vulnerability exists in the Graphics: ImageLib component of Firefox and Thunderbird, carrying a CVSS score of 9.8. Successful exploitation could allow remote code execution via crafted image content rendered by the affected browser or mail client, posing significant risk to any endpoint running unpatched versions.

A critical use-after-free vulnerability (CVE-2026-74940) exists in the Graphics: Text rendering component of Firefox and Thunderbird, carrying a CVSS score of 9.8. Successful exploitation could allow remote code execution, potentially enabling attackers to compromise systems that browse untrusted content or process malicious documents/emails.

A critical use-after-free vulnerability (CVE-2026-74936) exists in the WebAssembly component of Firefox's JavaScript engine, carrying a CVSS score of 9.8. The flaw affects multiple Firefox and Thunderbird release channels and has been patched in the latest versions, indicating high urgency for organizations to update immediately.

TrueConf Server contains a missing authentication vulnerability that allows a remote, unauthenticated attacker with network access to port 4307/TCP to execute arbitrary scripts on the server. This flaw has been added to CISA's Known Exploited Vulnerabilities catalog, indicating active exploitation in the wild, and requires urgent remediation ahead of the CISA-mandated due date of 2026-08-23.

TrueConf Server is vulnerable to a code injection flaw that allows an unauthenticated remote attacker to escape an isolated execution environment and run arbitrary code on the host via port 4307/TCP. The vulnerability has been added to CISA's Known Exploited Vulnerabilities catalog, indicating active exploitation in the wild, with remediation required by September 3, 2026.

SilkParasite is a newly identified cyber espionage operation targeting government bodies in Central Asia, first observed in late 2025. The campaign leverages seven distinct RAT families, five of which are previously undocumented, indicating a well-resourced threat actor with custom malware development capabilities.

OpenAI temporarily paused reinforcement learning (RL) training of its newest frontier models for two weeks to strengthen internal defenses and expand monitoring, citing growing risks as model capability increases. The move appears preventive, referencing a prior 'Hugging Face-like incident' as a cautionary precedent rather than disclosing an active breach or exploit.

Researchers demonstrated a remote Spectre-class microarchitectural side-channel attack against Cloudflare Workers that allows a malicious Worker to leak secret data, including JSON Web Tokens, from a co-located victim Worker in production at up to 12 bits per second. This represents a 360x throughput improvement over a 2021 proof-of-concept and confirms that multi-tenant serverless/edge compute platforms remain vulnerable to cross-tenant speculative execution leakage despite existing mitigations.

Sakura Internet, a major Japanese cloud and data center provider, disclosed unauthorized access to its sales management system, exposing contract and membership data for up to 1.36 million accounts. The breach affects a company that provides hosting and cloud infrastructure to numerous business customers, raising downstream exposure concerns.

A suspected ransomware affiliate is impersonating a legitimate data recovery firm called 'Ransom Busters,' contacting victims prior to public disclosure of breaches and offering fraudulent decryption keys and data deletion services for payment. This represents a secondary extortion layer that exploits victim desperation and confusion during active incident response, potentially resulting in double payment with no guarantee of data recovery or deletion.

OpenAI confirmed a major outage affecting ChatGPT, with users unable to log in, sign up, or access previous conversations. The incident appears to be a service availability failure rather than a security breach or exploitation of a vulnerability.

NSA, CISA, FBI, DOE, and EPA have issued a joint advisory warning of active threat actor targeting of Internet-exposed Siemens S7 Series PLCs (S7-200 through S7-1500) across U.S. critical infrastructure sectors. Threat actors are using AI-assisted development to rapidly generate exploitation scripts—built on the open-source snap7/python-snap7 library—that masquerade as legitimate OT monitoring tools to gain read/write access via the S7comm protocol, likely as reconnaissance and pre-positioning for future disruptive operations.

CISA has added CVE-2026-64849, a Server-Side Request Forgery (SSRF) vulnerability in MLflow, to its Known Exploited Vulnerabilities Catalog based on confirmed active exploitation. Federal agencies are required under BOD 26-04 to remediate this vulnerability on a prioritized basis, and CISA urges all organizations to do the same given active in-the-wild attacks.

A critical, easily exploitable vulnerability exists in Oracle Web Services Manager (Web Services Security component) affecting versions 12.2.1.4.0 and 14.1.2.0.0. An unauthenticated attacker with network access via HTTP can compromise the product, gaining unauthorized creation, deletion, modification, and full read access to all data accessible to Oracle Web Services Manager.

A critical unauthenticated remote vulnerability affects Oracle Identity Manager's Legacy UI component within Oracle Fusion Middleware, allowing full compromise via simple HTTP requests. With a CVSS score of 9.8, this flaw requires no authentication or user interaction, making it highly attractive for mass exploitation once technical details or proof-of-concept code emerge. Organizations running affected versions face risk of complete identity infrastructure takeover, including provisioning, credential, and access control data.

A critical vulnerability (CVE-2026-60720, CVSS 9.9) affects the OIM Legacy UI component of Oracle Identity Manager within Oracle Fusion Middleware, allowing a low-privileged attacker with network HTTP access to fully compromise the system. Due to a scope change, successful exploitation can impact other connected products beyond Oracle Identity Manager itself, making this a high-priority patching target for any organization running affected versions.

A critical, easily exploitable vulnerability in Oracle WebLogic Server allows unauthenticated attackers with network access via the T3 or IIOP protocols to fully compromise the server. With a CVSS score of 9.8 and no required user interaction or privileges, this flaw is highly likely to be weaponized rapidly, as historical WebLogic T3/IIOP vulnerabilities have been favored targets for mass exploitation and ransomware precursor activity.

CVE-2026-60591 is a critical, easily exploitable vulnerability in Oracle Hospitality Simphony POS software that allows unauthenticated attackers with network access to compromise data integrity and availability. Affected versions span 19.8 through 19.10.1, and successful exploitation can result in unauthorized data modification/deletion and denial of service. Organizations using Simphony in restaurant, hotel, or retail point-of-sale environments should prioritize patching due to the low complexity and lack of authentication required for exploitation.
