CVE-2019-1068: A remote code execution vulnerability exists in ...

CISA added CVE-2019-1068, a high-severity remote code execution flaw in Microsoft SQL Server, to its KEV catalog after confirming exploitation in the wild.

CVE-2019-1068 (CVSS 8.8, CWE-20) is an improper input validation flaw allowing unauthenticated RCE in Microsoft SQL Server 2014 SP2/SP3, 2016, and 2017 on 32-bit and x64 builds. Exploitation requires low complexity and low privileges with no user interaction, and CISA formally added it to the KEV catalog on August 26, 2026. The CVE was originally published on July 15, 2019 and carries an EPSS score of 52.8%. Administrators must inventory affected SQL Server assets and apply vendor patches on an accelerated timeline.

Critical ArangoDB Flaws Allow Authentication Bypass and Remote Code Execution as Root

Two critical ArangoDB flaws (CVSS 9.8 and 9.9) enable unauthenticated API access and root code execution; fixes shipped in version 3.12.11

Remedio researchers found two ArangoDB flaws: GHSA-rrgq-978q-36mq (CVSS 9.8), an authentication bypass caused by the server inconsistently interpreting URL-encoded '/_api' paths, and GHSA-rvhw-4hpw-9vrx (CVSS 9.9), which lets users with database write access run JavaScript tasks with root privileges via the isSystem flag. Chained, they allow administrative database access without credentials, theft of the root password hash, and root code execution, exposing files such as /etc/shadow, TLS keys and cluster signing material on the official container image. ArangoDB shipped fixes in version 3.12.11 on August 31, 2026, with advisories published September 6; CVE identifiers were still pending. Users on 3.12.10.1 or earlier should upgrade, restrict exposure and rotate potentially exposed credentials.

Critical ArangoDB Bugs Expose Entire Databases and Enable Remote Code Execution as Root

Two critical ArangoDB flaws (CVSS 9.8/9.9) allow unauthenticated API access and root-level code execution; fixed in 3.12.11.

Remedio researchers reported two critical ArangoDB flaws on August 23, 2026: an authentication bypass via URL-encoded underscores (%5f) in path parsing (GHSA-rrgq-978q-36mq, CVSS 9.8) and a task-execution flaw where a client-controlled isSystem flag lets JavaScript run in the internal context (GHSA-rvhw-4hpw-9vrx, CVSS 9.9). Chained, they allow unauthenticated database access, theft of root password hashes, and root-level code execution when arangod runs as root, such as in the official container image. Patches shipped August 31 in ArangoDB 3.12.11, with GitHub Security Advisories published September 6; CVE identifiers were pending at disclosure time.

Zoom Patches “Zoomsday” Zero-Click Flaw Enabling Remote Code Execution

Zoom patched CVE-2026-53413, a zero-click annotation flaw dubbed "Zoomsday" allowing remote code execution on meeting participants' devices across all platforms.

Zoom patched four vulnerabilities, including CVE-2026-53413, a stack buffer overflow in CAnnoFormatBlock::Deserialize in the annotation protocol that allows zero-click remote code execution on another participant's device. A Security also found CVE-2026-53414, a buffer overread enabling denial-of-service crashes, and CVE-2026-53415, a use-after-free Zoom had already discovered internally. Updates shipped for Workplace 7.1.5 and 7.0.6, Rooms 7.1.5, and Meeting SDK 7.1.5 across all supported platforms.

Elementor Pro Flaw Could Let Unauthenticated Attackers Upload PHP and Execute Code

Patchstack disclosed CVE-2026-32475 (CVSS 9.0), an unauthenticated file-upload flaw in Elementor Pro enabling PHP upload and RCE; fixed in version 4.2.2.

Patchstack researcher Tin Pham reported an unrestricted file upload flaw in Elementor Pro's Forms module (CVE-2026-32475, CVSS 9.0), affecting all versions up to and including 4.2.1. Submitting two file parts for one field bypasses the extension blocklist and writes attacker-controlled PHP into a public uploads directory, yielding unauthenticated remote code execution when a published Elementor page uses a Form widget with a File Upload field. A patched version 4.2.2 shipped August 19, 2026, a day after WordPress 7.0.4 fixed CVE-2026-65640 (CVSS 8.8), an RCE via Postscript file upload when Imagick and Ghostscript are in use.

Off Guard: Breaking LiteLLM from authentication bypass to cloud compromise

Wiz found LiteLLM auth bypass (CVE-2026-59822) and post-auth RCE (CVE-2026-59821) chainable to cloud compromise; the bypass is in CISA KEV with in-the-wild exploitation.

Wiz scanned roughly 3,074 internet-facing LiteLLM deployments and found 9.6% accepted the default master key sk-1234 or required no authentication, making post-auth attacks effectively pre-auth. The MCP endpoint accepts any Bearer token and grants a valid session (CVE-2026-59822), confirmed exploited in the wild via honeypots and added to CISA's Known Exploited Vulnerabilities catalog. Custom code guardrails allow post-auth root-level RCE via exec(compile(...)) (CVE-2026-59821), while pass-through endpoints lack URL validation, enabling cloud credential theft in post-auth scenarios. All assigned vulnerabilities have been patched; the research was presented at DEF CON 34.

Another Apache Log4j Vulnerability Is Actively Exploited in the Wild (CVE-2021

Apache Log4j 2 RCE CVE-2021-44228 is actively exploited via crafted JNDI lookups; Palo Alto Unit 42 urges upgrading to Log4j 2.17.1.

Unit 42 details CVE-2021-44228, an easily exploited remote code execution flaw in Apache Log4j 2 where attacker-supplied JNDI lookups in logged user input cause payload download and execution. Massive internet-wide scanning for unpatched systems has begun, with observed follow-on activity including information stealing, Cobalt Strike delivery, and coinmining. The recommended fix is Log4j 2.17.1, which also patches CVE-2021-45046, CVE-2021-45105, and CVE-2021-44832. Widely used Java software including Apache Struts, Solr, Druid, Flink, ElasticSearch, and Spring Boot is affected.
