PostgreSQL Fixes 12-Year-Old Logical Decoding Flaw Enabling Replication-Role Code Execution

PostgreSQL fixed CVE-2026-6471 (CVSS 7.2), a 12-year-old logical decoding flaw letting replication-role accounts execute arbitrary code as the database OS user.

PostgreSQL patched CVE-2026-6471 (CVSS 7.2), a flaw present since logical decoding shipped in 9.4 (2014) that lets an account with the REPLICATION attribute run arbitrary code as the database server's OS user when wal_level is logical. Versions before 18.6, 17.11, 16.15, 15.19, and 14.24 are affected; exploitation requires such an account, which backup, CDC, and monitoring tooling routinely holds. The fix adds an output_plugin_libraries whitelist, so administrators using non-default plugins such as wal2json and decoderbufs must add them and reload configuration after updating. Cyera Research, whose write-up names the flaw PostGREShell, demonstrated escalating a replication user to superuser with persistence; no PoC or KEV entry existed as of September 4.

WordPress Events Calendar Vulnerabilities Let Hackers Take Over 600,000 Websites

Two unauthenticated RCE flaws (CVSS 9.8) in The Events Calendar WordPress plugin threaten 600,000 sites; patched in 6.17.4.1.

Wordfence Argus disclosed two critical unauthenticated vulnerability chains in The Events Calendar WordPress plugin, tracked as CVE-2026-78006 and CVE-2026-78159, both scoring 9.8 CVSS. CVE-2026-78006 enables PHP object injection leading to RCE via a Lazy_Post_Collection gadget chain, while CVE-2026-78159 abuses Element_Classes::parse_array() to invoke wp_update_user() and reset the admin password. Exploitation works by injecting wp:legacy-widget Gutenberg markup through comments, using WordPress's moderation-preview hash to trigger the block before approval. StellarWP patched both flaws in version 6.17.4.1 after Wordfence's August 2026 disclosure.

VU#943094: ONLYOFFICE ownCloud integration plugin contains a Server-Side Request Forgery (SSRF) vulnerability

ONLYOFFICE's ownCloud integration plugin 9.12 has an SSRF flaw (CVE-2026-84282) letting authenticated admins probe internal networks; no patch exists yet.

CERT/CC published VU#943094 for a server-side request forgery in Ascensio System SIA's ONLYOFFICE ownCloud integration plugin version 9.12, tracked as CVE-2026-84282. The /apps/onlyoffice/ajax/settings/address endpoint does not validate the user-supplied document server URL, so an authenticated administrator can make the ownCloud server send arbitrary requests to localhost and internal hosts. Differences in error responses (connection failures vs SSL/TLS errors) let attackers enumerate open and closed TCP ports for internal reconnaissance. The vendor could not be reached, so no official patch is available; CERT recommends disabling the plugin and applying egress filtering until a fix ships.

Decade-old PostgreSQL flaw turns backup account into a backdoor

Cyera disclosed CVE-2026-6471, a decade-old PostgreSQL flaw letting REPLICATION-attribute accounts achieve RCE and superuser compromise, patched August 13.

Cyera Research's 'PostGREShell' flaw exists in PostgreSQL's logical replication output plugin loading, where the replication code path never called the library-path security check, allowing path traversal or UNC paths to load arbitrary code. A low-privilege backup account can achieve code execution on Windows, Linux, and macOS, then escalate to superuser with persistent backdoor access. CVE-2026-6471 affects versions back to PostgreSQL 9.4 (2014) and was patched in releases 18.6, 17.11, 16.15, 15.19, and 14.24 on August 13. CVSS is 7.2, and no exploitation of this specific CVE has been confirmed, though VirusTotal hunting found 114 malicious PostgreSQL plugins.

Jellyfin 12.0 Released With Security Fixes for Unauthorized File Access and XSS Flaws

Jellyfin 12.0 fixes unauthorized file access and web client XSS flaws, but requires careful upgrades due to breaking database migrations and plugin changes.

The open-source media server release prevents crafted requests from reading files outside designated directories, blocks unauthorized re-runs of the setup wizard, rejects plugin packages with unsafe names, strengthens parental control enforcement, and fixes cross-site scripting vulnerabilities in browser-based administration and media access workflows. Upgrades require a manual backup because the database schema migration is irreversible; supported paths start from version 10.10.7 or 10.11.x, and duplicate case-insensitive usernames will break migration. The release also retires legacy /emby/ and /mediabrowser/ routes, disables deprecated authentication by default, and targets .NET 10, requiring plugin rebuilds.
