CVE-2026-3502 — TrueConf Client Download of Code Without Integrity Check Vulnerability
High
CVSS 7.8
CISA KEV
TrueConf Client downloads application update code and applies it without performing verification. An attacker who is able to influence the update delivery path can substitute a tampered update payload. If the payload is executed or installed by the updater, this may result in arbitrary code execution in the context of the updating process or user.

Matched remediation archetype
Supply-chain, dependency, build, and update integrity
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace affected packages, source archives, build actions, plugins, installers, and updates from declared source to deployed artifact.
- Confirm provenance, signatures or digests, namespace ownership, lockfile resolution, registry configuration, and build-runner trust boundaries.
- Inventory direct, transitive, vendored, generated, and bundled copies across releases and distribution channels.
Remediate safely
- Move to a maintained trusted artifact or remove the dependency; pin immutable identities and verify provenance and integrity before use.
- Regenerate lockfiles and artifacts in a clean isolated build, minimize build credentials and network access, and produce an updated software bill of materials.
- Require reviewed update policy, protected publishing, and reproducible or independently attestable builds where supported.
