The Canadian Centre for Cyber Security updated its May advisory to warn that attackers are now actively exploiting a Roundcube Webmail flaw, CVE-2026-48842, four months after it was patched. Roundcube is a browser-based IMAP client used as the default mail interface by thousands of services and pre-installed with the cPanel hosting control panel. The flaw is a pre-authenticated SQL injection in the virtuser_query plugin that handles database-driven user lookups. Exploitation lets an unprivileged attacker bypass authentication, inject and run database commands, and steal data from Roundcube's database, without user interaction in high-complexity attacks. Roundcube fixed it in versions 1.6.16 and 1.7.1, and Shadowserver tracks over 523,000 exposed instances online.
Cisco warned that attackers are exploiting a critical zero-day in its Secure Email Gateway appliances that lets them run commands as root just by sending a crafted email. Tracked as CVE-2026-76461 and scored 9.8, the flaw is a SQL injection in the appliance's email-parsing logic, so an unauthenticated attacker needs no access to the management interface at all. It affects physical and virtual gateways in any configuration, and Cisco confirmed it was exploited as a zero-day before disclosure. CISA added it to its exploited-vulnerabilities catalog with a three-day federal deadline. Because successful attacks grant root, intruders can erase their own tracks, so Cisco urges inspecting mail logs for suspicious activity.
cPanel patched a critical flaw that lets an ordinary hosting account with mail privileges take root control of the whole server. Tracked as CVE-2026-67401 and scored 9.9, it is a SQL injection in the EmailTrack mail-tracking feature that lets an authenticated account create arbitrary files and escalate to code execution as root. It affects all supported cPanel and WHM versions. On a shared server, a single cheap hosting plan or one stolen webmail password can lead to full server takeover, exposing every other tenant's sites, databases, and data. It is the third cPanel flaw since late July that turns one authenticated tenant into root, and cPanel published no indicators to hunt for.
Attackers are exploiting a critical flaw in Sangoma Switchvox, a widely used enterprise VoIP phone-system platform, to run code on servers without any credentials. Tracked as CVE-2026-9586 and scored 9.3, it is an unauthenticated SQL injection in an internet-facing endpoint that concatenates user-controlled input directly into database queries, letting an attacker execute commands as the database superuser and drop a reverse shell. Researchers at Horizon3 saw exploitation begin on August 30 and warn that most of the roughly 4,000 internet-exposed Switchvox systems may already have been targeted. Sangoma patched the flaw in version 8.4.0.2 back in July, but many systems remain unpatched and reachable.
A flaw in All-in-One WP Migration and Backup, a WordPress plugin installed on millions of sites, can let an unauthenticated attacker take over a site. Tracked as CVE-2026-19949, it is a second-order SQL injection caused by incorrect handling of escaped characters when the plugin rewrites database content during a restore. An attacker plants crafted data through WordPress trackbacks, which triggers when an administrator exports and imports the site, both routine plugin operations. The injection can leak the plugin's secret import key through a public comment, letting the attacker import a malicious backup archive containing executable code and seize full control. ServMask fixed it in version 7.110, but many sites remain unpatched.
ServiceNow patched four flaws in its widely used AI Platform, three of them scored 10.0 and exploitable by an unauthenticated attacker with no user interaction. The first, CVE-2026-18885, is a code injection in the GraphQL Composite Data API that allows arbitrary code execution and access to instance data. The second, CVE-2026-18886, is an access-control flaw in the configuration image-upload processor that lets an attacker create or modify data and escalate privileges. The third, CVE-2026-74820, is a SQL injection allowing arbitrary queries against the instance database. ServiceNow fixed hosted instances itself, but self-managed customers must apply the updates. No exploitation of these three has been reported yet.
A newly disclosed zero-day in GeoServer, the widely used open-source geospatial server, is already drawing exploitation attempts, according to watchTowr. The flaw is a SQL injection issue that can lead to remote code execution, and it remains unpatched, with no CVE assigned yet. It was first disclosed publicly by a researcher on August 12, and attackers commonly begin probing internet-facing servers as soon as such details appear. GeoServer instances are frequently exposed to the internet to serve mapping and location data, which makes an unpatched code-execution flaw in the platform an attractive and reachable target. Defenders should treat exposed instances as at risk until a fix ships.
Metabase warned that a critical zero-day in its open-source business intelligence platform was exploited in the wild for data theft. Scored 10.0 and tracked only as GHSA-vwf4-m7j8-wcjf with no CVE assigned, so scanners relying on the national database will not flag it, the flaw is an unauthenticated SQL injection in the password-reset endpoint. A remote attacker with no credentials injects SQL into the application database, gains administrator access, and can steal the stored credentials for every database the instance connects to, then read and export their data. Metabase Cloud was attacked from around August 3 and is already patched; self-hosted versions 1.58 and later must upgrade.
Public exploit code is now available for wp2shell, a pair of WordPress core flaws that chain into pre-authentication remote code execution against a stock site with no plugins installed. CVE-2026-63030 is a route confusion bug in the REST API batch endpoint, which has shipped enabled by default since 2020, and CVE-2026-60137 is a SQL injection in the author parameter handling of WP_Query. Chained, an anonymous HTTP request can run code on the server. The chain affects WordPress 6.9.0 through 6.9.4 and 7.0.0 through 7.0.1, fixed in 6.9.5 and 7.0.2, and WordPress enabled forced automatic updates given the severity.
Qianxin XLab has documented a large-scale ClickFix campaign exploiting CVE-2026-26980, an SQL injection in Ghost CMS that was disclosed and patched on February 19. The vulnerability lets unauthenticated attackers read arbitrary database content including admin API keys, which are then used to inject malicious JavaScript into articles. More than 700 domains are confirmed compromised, including Harvard, Oxford, and Auburn universities and DuckDuckGo. Victim browsers receive a fingerprinted iframe overlay impersonating a Cloudflare prompt that instructs users to paste a command into the Windows command prompt, dropping DLL loaders, JS droppers, or the UtilifySetup.exe Electron-based payload. Two distinct activity clusters compete for compromised sites.
