Adobe Releases Emergency Update for Campaign Classic Fixing Multiple Critical Vulnerabilities
Adobe has released an emergency security update for Adobe Campaign Classic to address seven critical vulnerabilities, several of which received the maximum CVSSv3.1 base score of 10.0.
The company disclosed the issues on August 3, 2026, through a security advisory and urged immediate application of the new patches. The vulnerabilities impact on-premises installations running on Windows and Linux as well as the on-premises components in hybrid deployments.
Just days earlier, on July 29, Adobe had already shipped an emergency update (version 7.4.3 build 9398). However, both that release and all prior versions remain affected by the newly disclosed flaws, necessitating another round of updates.
The most severe issues include:
- CVE-2026-48331 – a server-side request forgery (SSRF) vulnerability
- CVE-2026-48323 – an input processing flaw in the template engine
- CVE-2026-48330 – an SQL injection vulnerability
All three received a CVSSv3.1 base score of 10.0. Adobe recommends that organizations running the affected versions apply the latest fixes without delay to prevent potential exploitation.

Unbound 1.26.1 Patches Critical DNSSEC Validator Flaw CVE-2026-81642 Enabling Remote Code Execution
NLnet Labs has released Unbound 1.26.1 to address CVE-2026-81642, a critical vulnerability in the DNSSEC validator that can cause service crashes and potential remote code execution. The flaw affects all versions up to and including 1.26.0 and is triggered when validating a malicious DNS zone. It resides in the handling of DNSKEY records, where a buffer overflow can occur during DNS response processing. The vulnerability carries a CVSS 4.0 score of 9.1 with a network attack vector, no privileges required, and no user interaction needed. Exploitation requires an attacker to control a malicious DNS zone that the resolver queries, which can lead to denial of service or RCE in the worst case. The update also includes fixes for eight additional security issues, including CVE-2026-82717 and CVE-2026-81634, both involving heap corruption.
BIND DNS Servers Receive Patches for 14 Vulnerabilities Including High-Severity DoS Flaws
The Internet Systems Consortium has released BIND 9 updates that address 14 vulnerabilities across multiple versions of the widely used DNS server software. Seven of the issues received a CVSS score of 7.5 and were rated high severity, while the remaining seven scored between 5.3 and 6.5. The most critical flaw allows an unauthenticated attacker to crash the named process with a single malformed SIG(0) request over DNS over HTTPS. Additional vulnerabilities enable cache poisoning through forged NXDOMAIN responses, downgraded secure delegations, and acceptance of unsigned answers, as well as resource exhaustion via uncontrolled cache growth and excessive CPU consumption. Affected releases span BIND 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, and 9.21.0 through 9.21.25. No workarounds exist, making immediate upgrades to versions 9.20.29, 9.21.26, or 9.20.29-S1 the only mitigation. The ISC reports no known exploitation in the wild and none of the flaws appear in CISA’s Known Exploited Vulnerabilities catalog.

pgAdmin 4 Database Management Tool Patches Multiple Vulnerabilities in Version 9.18
The development team behind pgAdmin 4, the popular management tool for PostgreSQL databases, has released version 9.18 to address multiple security issues. The update, published on September 17, 2026, includes fixes for four CVEs along with 29 total changes covering new features and bug resolutions. One vulnerability, tracked as CVE-2026-86863, stems from insufficient web server authentication that trusts external HTTP headers, enabling attackers to bypass login and impersonate administrators without passwords. A second issue, CVE-2026-86864, allows command injection through the backup feature when database names are passed as arguments, potentially leading to unauthorized file writes or exfiltration of connection passwords. The update is available now from the official pgAdmin repository.
