Cisco Warns of Seven ClamAV Flaws, Two With Public PoCs
Cisco warns of seven ClamAV denial-of-service flaws in Secure Endpoint Connector, two with public PoCs; patches due in August.
Cisco warned that seven ClamAV denial-of-service vulnerabilities, tracked as CVE-2026-20337 through CVE-2026-20339 and CVE-2026-20345 through CVE-2026-20348, affect the Secure Endpoint Connector on Windows, macOS and Linux. Two flaws, CVE-2026-20337 (CVSS 7.5, out-of-bounds write) and CVE-2026-20338 (memory double-free), have public proof-of-concept code, but Cisco PSIRT reports no evidence of malicious exploitation. Fixes shipped in ClamAV 1.5.4, with Cisco patches due in August and no workaround available. Windows is rated high risk because ClamAV runs with elevated privileges there.

Alby Hub Critical Flaw Could Let Attackers Take Over Internet-Exposed Bitcoin Wallets
Alby warns a critical flaw in internet-exposed Alby Hub Bitcoin wallets (v1.7.0–v1.18.5) could allow takeover and fund theft; update to v1.24.0.
Alby disclosed a critical flaw in Alby Hub, its self-hosted Lightning wallet, affecting versions v1.7.0 through v1.18.5 when the management interface is reachable from the internet. The flaw could let attackers take over a wallet and send its funds; one affected user has been reported so far, with no word on losses. Versions v1.19.0 and later contain the fix, and Alby advises updating to v1.24.0, binding port 8080 to localhost or firewalled sources, and changing unlock passwords on previously exposed hubs. Full technical details will be published later under responsible disclosure.
