Parallels Desktop flaw hands any local user root on a Mac (CVE-2026-90894)

CVE-2026-90894 in Parallels Desktop for Mac lets any local user gain root via argument injection; patched in v27.0.0, PoC withheld.

JFrog researchers disclosed CVE-2026-90894, an argument injection flaw in Parallels Desktop for Mac v26.4.0 on Apple silicon that lets any local user gain root on the host. The chain combines a world-writable Unix socket for prl_disp_service (which runs as root), weak peer-credential authentication, and argument injection via --use-compress-program in the appliance extraction tar path. Alludo fixed the flaw in Parallels Desktop v27.0.0 in early September 2026; JFrog published technical details but withheld its proof-of-concept script.

Telegram Desktop XSS Vulnerability Lets Attackers Steal Entire Chat Histories

Stored XSS in Telegram Desktop HTML chat exports (CVSS 8.2) could let attacker-controlled inline keyboard buttons steal full chat histories.

ExPatch researchers Denis and Aleksander Rostilov found a stored XSS in Telegram Desktop's HTML chat export pipeline affecting builds before Beta 6.9.4 and Stable 7.0.1. Unsanitized inline keyboard button text becomes executable JavaScript when a user exports a chat and opens the HTML file in a browser, exposing messages, metadata, and local file paths, and enabling phishing overlays. Telegram patched the issue in commit 8457d13a during July 2026; no CVE had been assigned at disclosure time.

Telegram Desktop Flaw Lets Attackers Steal Chat Messages Through Poisoned HTML Exports

Telegram Desktop XSS in bot inline keyboard buttons let attackers steal chat content from exported HTML archives; patched in 7.0.1.

ExPatch researchers Denis and Aleksander Rostilov found a stored cross-site scripting flaw in Telegram Desktop's HTML export feature, present since version 4.15.1 (March 2024). JavaScript hidden in bot inline keyboard button text executes when a user opens an exported chat HTML file with JavaScript enabled, exposing messages, metadata, and enabling DOM manipulation such as fake verification screens. Fixes shipped in Desktop Beta 6.9.4 (July 3, 2026) and Stable 7.0.1 (July 14, 2026), but previously exported HTML files remain unsafe.

BIND 9.20.29 Fixes 14 Security Flaws Enabling DNSSEC Bypass and Denial-of-Service Attacksnew

ISC released BIND 9.20.29 patching 14 flaws, including two DNSSEC validation bypasses enabling cache poisoning and multiple denial-of-service bugs.

Internet Systems Consortium shipped BIND 9.20.29 (and 9.21.26) fixing 14 vulnerabilities affecting recursive and DNSSEC-validating resolvers. Key flaws include CVE-2026-77119 (CVSS 5.9), which lets injected NSEC3 records from sibling zones make forged answers appear validated, and CVE-2026-19941, enabling forged DNSSEC-validated NXDOMAIN responses. DoS issues include CVE-2026-19668 (CVSS 5.3, CPU exhaustion via crafted DS/DNSKEY key tags) and cache bloat bugs CVE-2026-81736 and CVE-2026-81563; CVE-2026-1903 fixes partially unsigned TSIG zone transfers and CVE-2026-78301 fixes out-of-zone record serving. ISC reports no active exploitation and says CVE-2026-19668 and CVE-2026-77119 have no workarounds, so upgrading is the only reliable mitigation.
