Summary
An authenticated command injection vulnerability in TP-Link Archer BE800 V1 allows an attacker with administrative access to execute arbitrary system commands with root privileges by injecting shell metacharacters via a VPN connection. Successful exploitation may enable persistent backdoors, credential theft, LAN reconnaissance, and router-assisted attacks against connected devices.
Risk Assessment
The risk for the organization includes full compromise of the router, which can lead to persistent attacker presence in the network, credential theft, and attacks on other devices in the LAN.
Recommendation
It is recommended to immediately update the firmware of the TP-Link Archer BE800 router to the latest version with fixes. Also restrict administrative access to trusted users and use strong passwords.

D-Link DNS-340L and DNS-345 (versions 1.01B04/1.03B06/1.04.B02/1.05b04) have a vulnerability in /cgi-bin/virtual_vol.cgi (Virtual Volume Handler). Manipulation of arguments f_sharename/f_target/f_name leads to OS command injection. Remote exploitation is possible, and the exploit has been publicly disclosed.
- CVE-2026-49003Critical
Attackers can exploit command injection vulnerabilities to delete core system runtime files, causing the monitoring module to crash. They can also gain root privileges to steal configuration passwords (e.g., SNMP) and tamper with critical system parameters, leading to abnormal operation of the entire power system.

ToolJet before v3.16.208 fails to validate that authenticated users belong to the organization specified in the organizationId path parameter of tooljet-db endpoints, allowing any Builder user to read, modify, and delete tables across tenant boundaries. Attackers can extract victim organization IDs from public app endpoints, then exploit schema operation endpoints to disclose schemas, plant malicious tables, corrupt schemas, or permanently destroy data.
- CVE-2026-82872Critical
ToolJet before v3.16.208 fails to validate that the path organizationId matches the authenticated user's workspace before performing ToolJet DB table operations. A workspace admin can create, view, and delete database tables in another workspace by replacing the organizationId parameter in table-management API requests.
- CVE-2026-82870Critical
ToolJet before v3.16.208 fails to validate organizationId ownership in database write and destroy routes, allowing any builder-role user to create, alter, or drop tables in other organizations' databases. Attackers can exploit missing guards to permanently delete tables, insert arbitrary data, and modify schemas across tenant boundaries on shared instances.

@hulumi/policies before 1.3.2 fail to fully inspect inline and attached IAM policy evidence for the administrator-policy guardrail. Attackers can craft admin-equivalent policy paths that bypass policy evaluation controls.
- CVE-2026-82859Critical
hulumi before v1.3.2 contain a deployment SCP template that allows tag-on-create bypasses for hulumi:iac-role protections. Attackers can bypass intended IAM boundary restrictions by exploiting the weakened SCP template in downstream deployments.

@hulumi/drift before 1.3.2 accept externally supplied execute plans without sufficient provenance validation, allowing untrusted reconciliation input to be treated as trusted. Attackers can supply malicious execute plans that bypass security checks to perform unsafe reconciliation operations.
- CVE-2026-82857Critical
A privilege escalation vulnerability in hulumi before v1.3.2 exists in the weekly integration IAM policy, allowing role lifecycle operations on af-e2e-* roles without sufficient boundary restrictions. Attackers with the documented principal can create persistent higher-privilege roles in the sandbox account.
- CVE-2026-82856Critical
A vulnerability in @hulumi/policies before 1.3.2 fails to properly validate set-qualified AWS IAM condition operators in GitHub OIDC trust policies. Attackers can use ForAnyValue:StringLike operators to hide wildcard GitHub Actions OIDC subject conditions from security guardrails.
