  Missing authorization in ScreenConnect client allows unauthorized file execution
  CVE-2026-84869 is a critical authorization flaw (CWE-862 missing authorization, CWE-269 improper privilege management) in the ScreenConnect client, the endpoint-side agent of ConnectWise's widely used remote access and remote support platform, in which files can be transferred to a machine and executed during an active remote session without the expected authorization or without confirmation by the Host (technician). It is triggered in certain circumstances during an active session, with a network attack vector, low attack complexity, low privileges required, and no user interaction per the CVSS 3.1 vector. An actor who obtains or already holds access to a session context could thereby push and run files on the managed endpoint, potentially achieving code execution with high confidentiality, integrity, and availability impact (CVSS 3.1 score 9.9, scope changed). Only endpoints running the ScreenConnect client are affected; ScreenConnect servers are not impacted, and the affected client version ranges are governed by ConnectWise security advisory AV26-903 (not enumerated in the available data). The flaw is not currently known to be exploited: it is not in CISA KEV, no public proof of concept is known, and EPSS assigns a modest 0.4% probability of exploitation within the next 30 days (32nd percentile).

  Token Scope Validation Flaw Enables Privilege Escalation in JFrog Artifactory
  JFrog Artifactory (Self-Hosted) versions before 7.133.11 fail to validate a token's scope, checking only the token's signature and issuer, which constitutes an incorrect authorization flaw (CWE-863). A remote, authenticated user with low privileges can obtain or present a token whose scope is never verified, bypassing authorization checks and escalating to higher privileges. Successful attackers gain administrative control of the Artifactory instance; in observed attacks this flaw has been chained with CVE-2026-42018 and CVE-2026-82329 to bypass authentication, take admin control, and deploy backdoor malware. Only self-hosted Artifactory deployments are within the stated affected scope. Exploitation is confirmed in the wild and the vulnerability was added to CISA's KEV catalog on 2026-09-11, although no public proof-of-concept code is known.

  Improper Authentication in JFrog Artifactory Exposes Internal Anonymous Tokens
  JFrog Artifactory contains an improper authentication flaw (CWE-287) in which the server may return its internal anonymous-user token to an unauthenticated caller, even on instances where anonymous access is disabled. An attacker triggers the issue by sending unauthenticated requests to the affected Artifactory interface over the network; the vector requires no privileges or user interaction and is of low complexity. Successful abuse yields the internal anonymous-user token, which can then be used to reach sensitive resources (such as repositories or artifacts) that should be protected when anonymous access is disabled, with high confidentiality impact but no integrity or availability impact. Any organization running an affected JFrog Artifactory deployment - particularly those relying on disabled anonymous access as a control - is affected, though only instances where the vulnerable endpoint is reachable are actually exposed. Exploitation has been reported in the wild as part of an ongoing Artifactory attack campaign alongside CVE-2026-42016 and CVE-2026-82329, although there is no public PoC and the flaw is not yet in the CISA KEV catalog.
