CVE-2026-73195 Sep 14, 13:23 HIGH This Week

CSV formula injection in Apache Syncope allows authenticated low-privilege users to embed spreadsheet formula payloads in their own user attributes. When an administrator exports users to CSV and opens the file in a spreadsheet application such as Microsoft Excel or LibreOffice Calc, the stored formula is evaluated in the spreadsheet's execution context - enabling data exfiltration from the spreadsheet or arbitrary command execution on the administrator's workstation. No public exploit code has been identified at time of analysis, and SSVC classifies exploitation status as none and not automatable.

CVE-2026-69821 Sep 08, 18:19 HIGH PATCH This Week

Local privilege escalation in Active Directory Certificate Services (AD CS) on Windows enables an authenticated low-privileged user to gain full system control (C:H/I:H/A:H) without user interaction. The root cause is CWE-116 - improper encoding or escaping of output - within the AD CS component, which Microsoft has patched across a broad range of Windows 10 and Windows Server releases from 2012 through 2025. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity (AC:L) makes this straightforward to exploit once an attacker has local access.

CVE-2026-84292 Sep 02, 20:17 HIGH PATCH This Week

URI authority injection in fast-uri allows an attacker-supplied port value containing delimiter characters to demote the intended host to userinfo and redirect the parsed authority to an attacker-controlled hostname, bypassing downstream re-validation because both fast-uri and Node.js's built-in URL parser silently accept the malformed output as well-formed. Applications in the Fastify ecosystem that build URIs from parts — passing untrusted data into the port field of a URI object through serialize, normalize, or equal — on fast-uri versions before 2.4.6, 3.1.7, or 4.1.4 are affected. No public exploit has been identified at time of analysis, and the CVE is not listed in CISA KEV; vendor-released patches are available across all three active release lines.

Namespace injection in the MongoDB C++ Driver (all versions prior to r4.5.1) allows low-privileged users of affected multi-tenant applications to redirect database operations to unintended namespaces. The driver fails to validate caller-supplied database and collection name identifiers against '.' and NUL byte characters, enabling an attacker who can influence those identifiers to access or modify another tenant's data. No public exploit has been identified and the vulnerability is not listed in the CISA KEV catalog; a vendor-released patch is available in r4.5.1.

CVE-2026-81685 Aug 27, 14:50 PyPI CRITICAL PATCH Act Now

Output-encoding text injection in jahlives openssl_encrypt before 1.4.9 lets an attacker forge the desktop GUI's irreversible-removal confirmation dialog. By embedding bidirectional-override and line-separator control characters in the recovery-slot identifier of a crafted encrypted file, an attacker can rewrite the warning text a victim sees, tricking them into approving destructive file-removal operations. No public exploit is identified at time of analysis, and the record is not in CISA KEV; the published 9.3 CVSS 4.0 rating appears inflated relative to the spoofing-only mechanism.

Improper output encoding in the Apache CloudStack management UI's Instance Reset Password feature allows injection of unescaped output that can expose sensitive data or manipulate the interface. It affects Apache CloudStack 4.15.1.0 through 4.20.3.0 and 4.21.0.0 through 4.22.1.0, an open-source IaaS cloud orchestration platform. There is no public exploit identified at time of analysis, and EPSS exploitation probability is low (0.14%, 4th percentile); vendor-released patches exist in 4.20.3.1 and 4.22.1.1.

Code injection in remorses/genql (the @genql/cli TypeScript GraphQL client generator) before 6.3.4 lets an actor who controls the GraphQL schema fed to genql smuggle arbitrary TypeScript/JavaScript into the generated schema.ts file, which then executes when a downstream consumer bundles and imports the client. The flaw stems from GraphQL type/field descriptions containing a `*/` sequence that breaks out of the generated JSDoc comment block. There is no public exploit identified at time of analysis and it is not in CISA KEV; the issue was responsibly disclosed (issue #197) and reported by CISA (cisa-cg), with a vendor patch in 6.3.4.

It is a bypass of the incomplete fix for CVE-2022-4318, whose HOME sanitization was insufficient. No public exploit identified at time of analysis and it is not listed in CISA KEV.

Arbitrary code execution in Adobe Commerce, Adobe Commerce B2B, Magento Open Source, and the Adobe Commerce Webhooks Plugin stems from improper output encoding/escaping (CWE-116) and lets a high-privileged attacker run code in the context of the current user with no user interaction. Because the scope is changed, exploitation can affect components beyond the initially vulnerable one, and Adobe rates it CVSS 9.1. There is no public exploit identified at time of analysis, it is not in CISA KEV, and EPSS is low (0.90%, 56th percentile), so risk is currently theoretical/targeted rather than mass-exploited.

Ban-list poisoning in OpenWrt's luci-app-banip (banIP) before 1.8.10 lets an unauthenticated remote attacker steer the automated IP-blocking engine at an arbitrary victim. Because the awk-based log monitor grabs the first IPv4 address it finds on a log line regardless of field position, an attacker can embed a spoofed IP inside an attacker-controlled field such as a login username; banIP then bans that injected address while the real attacker's source IP is never blocked. Reported by VulnCheck with a vendor patch available; no public exploit code or active exploitation is identified at time of analysis.
