A high-severity security flaw has been disclosed in MongoDB that could allow unauthenticated users to read uninitialized heap memory. The vulnerability, tracked as CVE-2025-14847 (CVSS score: 8.7), has been described as a case of improper handling of length parameter inconsistency , which arises when a program fails to appropriately tackle scenarios where a length field is inconsistent with the actual length of the associated data. "Mismatched length fields in Zlib compressed protocol headers may allow a read of uninitialized heap memory by an unauthenticated client," according to a description of the flaw in CVE.org. The flaw impacts the following versions of the database - MongoDB 8.2.0 through 8.2.3 MongoDB 8.0.0 through 8.0.16 MongoDB 7.0.0 through 7.0.26 MongoDB 6.0.0 through 6.0.26 MongoDB 5.0.0 through 5.0.31 MongoDB 4.4.0 through 4.4.29 All MongoDB Server v4.2 versions All MongoDB Server v4.0 versions All MongoDB Server v3.6 versions The issue has b...

A critical security flaw has been disclosed in LangChain Core that could be exploited by an attacker to steal sensitive secrets and even influence large language model (LLM) responses through prompt injection. LangChain Core (i.e., langchain-core ) is a core Python package that's part of the LangChain ecosystem, providing the core interfaces and model-agnostic abstractions for building applications powered by LLMs. The vulnerability, tracked as CVE-2025-68664, carries a CVSS score of 9.3 out of 10.0. Security researcher Yarden Porat has been credited with reporting the vulnerability on December 4, 2025. It has been codenamed LangGrinch . "A serialization injection vulnerability exists in LangChain's dumps() and dumpd() functions," the project maintainers said in an advisory. "The functions do not escape dictionaries with 'lc' keys when serializing free-form dictionaries." "The 'lc' key is used internally by LangChain to mark ser...

Fortinet on Wednesday said it observed "recent abuse" of a five-year-old security flaw in FortiOS SSL VPN in the wild under certain configurations. The vulnerability in question is CVE-2020-12812 (CVSS score: 5.2), an improper authentication vulnerability in SSL VPN in FortiOS that could allow a user to log in successfully without being prompted for the second factor of authentication if the case of the username was changed. "This happens when two-factor authentication is enabled in the 'user local' setting, and that user authentication type is set to a remote authentication method (eg, LDAP)," Fortinet noted in July 2020. "The issue exists because of inconsistent case-sensitive matching among the local and remote authentication."

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a security flaw impacting Digiever DS-2105 Pro network video recorders (NVRs) to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2023-52163 (CVSS score: 8.8), relates to a case of command injection that allows post-authentication remote code execution. "Digiever DS-2105 Pro contains a missing authorization vulnerability which could allow for command injection via time_tzsetup.cgi," CISA said. The addition of CVE-2023-52163 to the KEV catalog comes in the multiple reports from Akamai and Fortinet about the exploitation of the flaw by threat actors to deliver botnets like Mirai and ShadowV2 . According to TXOne Research security researcher Ta-Lun Yen, the vulnerability, alongside an arbitrary file read bug (CVE-2023-52164, CVSS score: 5.1), remains unpatched due to the device reaching end-of-life (EoL) status. Successfu...

A critical security vulnerability has been disclosed in the n8n workflow automation platform that, if successfully exploited, could result in arbitrary code execution under certain circumstances. The vulnerability, tracked as CVE-2025-68613 , carries a CVSS score of 9.9 out of a maximum of 10.0. Security researcher Fatih Çelik has been credited with discovering and reporting the flaw. The package has about 57,000 weekly downloads, according to statistics on npm. "Under certain conditions, expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime," the maintainers of the npm package said . "An authenticated attacker could abuse this behavior to execute arbitrary code with the privileges of the n8n process. Successful exploitation may lead to full compromise of the affected instance, including unauthorized access to sensitive data, modification of w...
