PoC Exploit Released for Android CVE-2026-0075 Allowing Contact Theft Without READ_CONTACTS Permission

A researcher has published a proof-of-concept exploit for CVE-2026-0075 affecting Android 14, 15, 16 and 16 QPR2. The flaw resided in the ContactsProvider2 component and enabled local applications to extract contact database entries through SQL injection and verbose SQLite error responses, bypassing the need for any user-granted permissions. Google rated the issue high severity and addressed it in the June 2026 security bulletin by stripping detailed JSON error information from responses to unprivileged apps. The publicly available PoC on GitHub deliberately avoids requesting READ_CONTACTS or WRITE_CONTACTS and is intended strictly for lab comparison of patched versus vulnerable builds. No confirmed in-the-wild exploitation has been observed yet, but the release of working code increases risk for devices running older firmware. Users are advised to verify that their devices have received the security patch dated 5 June 2026 or later.

A researcher has published a proof-of-concept exploit for vulnerability CVE-2026-0075 in Android. The flaw resided in the system component ContactsProvider2 and allowed a local application to reach the contacts database via SQL injection even when the user had never granted the READ_CONTACTS permission.

No additional user interaction or confirmation dialogs were required. The vulnerability stemmed from overly verbose SQLite error messages returned by ContactsProvider2 when specially crafted queries triggered database errors. By analyzing these responses, an application without any contact permissions could gradually reconstruct entries from the contacts database.

Google assigned the issue a high severity rating. It affects Android 14, Android 15, Android 16 and Android 16 QPR2, according to the June 2026 Android security bulletin. The official patch removes detailed JSON error information from responses sent to applications lacking contact access rights, replacing it with a generic message.

The PoC exploit published on GitHub intentionally does not request READ_CONTACTS or WRITE_CONTACTS permissions. Its author designed it for controlled laboratory testing to compare the behavior of patched and vulnerable builds. The researcher notes that a successful test on one device does not prove the vulnerability exists on every smartphone running the same Android version.

No confirmed cases of real-world exploitation of CVE-2026-0075 have been observed so far. However, the availability of public exploit code makes it unrealistic to expect older, unpatched firmware to remain safe. Users should check their device security update level in settings and ensure installation of the patch dated 5 June 2026 or newer.

CISA Adds Cisco Secure Firewall and GitLab Flaws to Known Exploited Vulnerabilities Catalog

The U.S. Cybersecurity and Infrastructure Security Agency has added two actively exploited vulnerabilities to its Known Exploited Vulnerabilities catalog. CVE-2026-76418 affects Cisco Secure Firewall ASA and FTD software, allowing unauthenticated attackers to trigger device reboots and denial-of-service conditions. CVE-2026-97229 impacts GitLab through an integer overflow tied to insufficient regex validation in CI/CD configurations, enabling remote code execution without authentication. CISA notes that the GitLab issue stems from an underlying flaw in the Ruby/Onigmo dependency and may affect additional products. Organizations are urged to apply patches immediately to prevent further exploitation in the wild.

Telegram for Android Patches Voice Call Vulnerability Enabling Code Execution

Security researchers at NebuSec disclosed a vulnerability in Telegram for Android that allowed remote code execution after a victim answered a voice call. The flaw affected versions from 8.6.2 through 12.10.3 and was fixed in release 12.10.4 at the end of September. The issue stemmed from improper handling of MediaState service messages that carry microphone, camera, and video rotation data during calls. When a required field was missing, the application accessed invalid memory. NebuSec discovered the bug using its Code Security product running on a GPT-5.4 model and confirmed exploitation on ARM64 Android devices for personal calls. A demonstration showed the string “HACKED BY NEBUSEC” appearing roughly 30 seconds after the call was accepted. The vulnerability is unrelated to the earlier animated-sticker attack vector.

Yandex Patches Millions of Stations After eMudhra Certificate Keys Compromised

Yandex has automatically deployed security updates to millions of its smart speakers and partner televisions running YaOS between October 21 and 23. The patches address compromised intermediate certificates issued by eMudhra whose private keys consisted of trivial values from 1 to 255. Attackers who obtained these keys could generate fraudulent certificates and perform man-in-the-middle attacks against device HTTPS traffic. Enthusiasts demonstrated that local network control combined with the certificates allowed replacement of server configuration, activation of ADB, and acquisition of root access on the devices. The update removes trust in the affected certificates, overwrites compromised system files, and disables the debug interface. A factory reset restores the vulnerable firmware, so Yandex advises against resets without a compelling reason.
