Atlassian October Security Bulletin Flags 176 Third-Party Library Vulnerabilities Across Jira, Confluence and Bitbucket

Atlassian released its October security bulletin detailing 176 vulnerability entries distributed across seven products including Jira, Confluence, Bamboo, Bitbucket, Crowd, Fisheye and Crucible. Of these, 162 entries carry high severity and 14 are rated critical, though the total does not represent 176 unique flaws because the same identifiers recur when multiple products share the same third-party library. All critical issues originate in external components rather than Atlassian code, with the most severe being CVE-2026-65637 in the Coyote component of Apache Tomcat used by Confluence, which allows interception of server-client connections. Affected versions and corresponding fixes were published for Confluence Data Center, Bamboo, Bitbucket Data Center, Jira Software and Jira Service Management, with the company stressing that administrators must compare exact build numbers against the full corrected-version table. No exploitation of the listed issues had been reported as of 22 October, and Atlassian classifies the inherited exposure from third-party libraries as lower priority, issuing separate critical alerts only for immediate-risk cases.

Top 10 Security Stories: Critical Flaws in PaperCut NG/MF, Chrome, WatchGuard and Others Dominate Week

Security NEXT has published its weekly ranking of the ten most-read articles between August 30 and September 5 2026. The list is led by a critical vulnerability in PaperCut NG/MF that is already being exploited in the wild. Google Chrome received two separate updates addressing 38 vulnerabilities, including two rated Critical and one zero-day. WatchGuard Fireware OS, SonicWall SMA 1000, Cisco IOS XR and Apache Tomcat also received urgent patches for severe flaws. Three real-world incidents made the top ten: a customer-data breach at 01 Bank, a ransomware infection at Hands HD and a suspected cloud leak at Corona. The ranking reflects strong reader interest in both newly disclosed vulnerabilities and confirmed exploitation cases.

Weekly Roundup: Next.js Leads Critical Vulnerability Reports as Chrome, Tomcat, and PostgreSQL See Major Patches

Security NEXT has published its list of the ten most-read articles for the week of August 23-29, 2026. The top story covered multiple serious vulnerabilities in Next.js that prompted an accelerated release schedule. Other high-interest items included a critical flaw in Zscaler Client Connector, several issues in Apache Tomcat rated critical, and Google’s Chrome 152 update fixing 327 vulnerabilities. Additional reports highlighted a ransomware incident at a systems development firm, flaws in SKYSEA Client View, 28 vulnerabilities fixed in PostgreSQL, and confirmed exploitation of six known flaws in SQL Server and NetScaler. The list also featured a vulnerability in the Android version of the Digital Agency’s My Number Point app and warnings about active exploitation of a WebLogic module flaw.

Multiple Vulnerabilities Found in Apache Tomcat, Four Rated Critical by CISA

Apache Tomcat has received updates addressing 11 vulnerabilities across versions 11.0.25, 10.1.59, and 9.0.121. The Apache Software Foundation rated four issues as Important, while CISA assigned Critical severity to four CVEs based on CVSS v3.1 scores reaching 9.8. The flaws include authentication bypasses, access control evasion due to path evaluation order, off-by-one errors, and HTTP/2 resource leaks leading to denial of service. One vulnerability was disclosed earlier in July, with the remaining ten detailed on August 25. Moderate and Low severity issues were also patched in the same releases. The discrepancies in severity ratings between the vendor and CISA highlight differing risk assessments for the same CVEs.

CISA Adds Three Actively Exploited Vulnerabilities to KEV Catalog Affecting Langflow, Apache Tomcat and N-central

The U.S. Cybersecurity and Infrastructure Security Agency has added three known exploited vulnerabilities to its KEV catalog, urging federal agencies to apply patches by August 7, 2026. CVE-2026-9198 affects the AI application development platform Langflow and allows unauthenticated attackers to chain API calls, obtain tokens, and execute arbitrary code. CVE-2026-34486 impacts Apache Tomcat and enables bypass of the EncryptInterceptor, leaving cluster node communications unencrypted. CVE-2026-18556 in N-able N-central permits authentication bypass through alternate channels, while an incomplete fix introduced CVE-2026-18577, which was added to the catalog one day earlier. All three issues have confirmed exploitation in the wild.
