CVE-2026-41103 Incorrect implementation of authentication algorithm in Microsoft SSO Plugin for Jira & Confluence allows an unauthorized attacker to elevate priv CRITICAL 9.1 0.1% 51
CVE-2026-42864 Server-side request forgery combined with missing authentication in firefighter-incident Python package allows unauthenticated remote attackers to exfiltrate AWS IAM credentials from cloud metadata endpoints. The `/api/v2/firefighter/raid/jira_bot` endpoint accepts arbitrary URLs in the `attachments` parameter, fetches them server-side without validation, and uploads responses as Jira attachments — enabling SSRF against internal services including `http://169.254.169.254/` (AWS EC2 Instance Metadata Service). Vendor-released patch (version 0.0.54) enforces authentication and validates attachment URLs to block private/link-local/loopback addresses. No public exploit identified at time of analysis, but exploitation is trivial given detailed advisory with exact vulnerable code paths. CRITICAL 9.9 0.1% 50
CVE-2026-44179 Remote code execution in XWiki Pro Macros (com.xwiki.pro:xwiki-pro-macros) versions >=1.13 and <1.14.5 allows any authenticated user with page-edit rights to execute arbitrary Groovy code via the excerpt-include macro, which fails to escape the included page's title and renders excerpt content with the macro's elevated rights. A working proof-of-concept is published in the GHSA advisory demonstrating injection through both a crafted page title and excerpt body. No public exploit identified at time of analysis as actively used, but the publicly available exploit code exists in the advisory itself. CRITICAL 9.9 &ndash; 50
CVE-2026-21571 Remote code execution in Atlassian Bamboo Data Center versions 9.6.0 through 12.1.0 allows authenticated attackers to execute arbitrary OS commands via command injection vulnerability. The attack requires low-privilege authentication (PR:L) but no user interaction, enabling complete system compromise across confidentiality, integrity, and availability with cross-scope impact (SC:H/SI:H/SA:H indicating container escape or lateral movement potential). Atlassian has released patches for three major version branches (9.6.25, 10.2.18, 12.1.6). No active exploitation confirmed in CISA KEV at time of analysis, though the authenticated nature and critical CVSS 9.4 score warrant immediate patching for internet-exposed instances with broad user access. CRITICAL 9.4 1.1% 48
No patch
CVE-2026-12225 Two-factor authentication bypass in syracom AG Secure Login (2FA) plugin 3.4.0.x for Atlassian Jira, Confluence, and Bitbucket allows an attacker holding valid first-factor credentials to skip the 2FA challenge entirely by injecting strings like 'AtlassianMobileApp' or 'JIRA' into the HTTP User-Agent header. The plugin treats such requests as mobile-app traffic and waives 2FA enforcement on protected web resources, effectively neutralizing the security control the plugin exists to provide. No public exploit identified at time of analysis, but the technique is trivial to reproduce from the public advisory text. HIGH 8.7 0.4% 44
CVE-2025-58175 Server-Side Request Forgery in GeoServer 2.26.x prior to 2.26.4 and 2.27.x prior to 2.27.3 allows unauthenticated remote attackers to coerce the server into issuing HTTP requests to attacker-chosen destinations by abusing weak prefix matching of the proxy base URL inside the XML entity resolver. No public exploit identified at time of analysis, and EPSS exploitation probability sits at 0.06% (19th percentile), but the trivial network-only attack vector and default-enabled ENTITY_RESOLUTION_ALLOWLIST since 2.25.0 raise the realistic exposure for internet-facing instances. HIGH 8.2 0.1% 41
CVE-2026-48048 Information disclosure in XWiki Platform's LiveTableResults macro allows unauthenticated remote attackers to reconstruct user password hashes and salts one bit at a time by sending approximately 768 crafted requests with manipulated class-per-property parameters. This is a bypass of the prior fix for GHSA-5cf8-vrr8-8hjm, which failed to account for an alternate parameter path. No public exploit is identified at time of analysis, but the technique is fully described in the vendor advisory. HIGH 7.5 0.0% 38
CVE-2025-27511 Remote code execution in GeoServer (versions prior to 2.27.0) with the DB2 extension installed allows authenticated administrators to perform a JNDI injection attack via a crafted DB2 JDBC connection URL submitted through the Vector Data Sources page, ultimately triggering Java deserialization of untrusted data and arbitrary code execution. No public exploit identified at time of analysis, and the vulnerability is not on CISA KEV, but the attack pattern follows well-known JNDI/Log4Shell-style RCE techniques. Risk is meaningful only where the DB2 extension is deployed and an administrative account is reachable. HIGH 7.2 0.4% 36
CVE-2025-52465 Arbitrary file write in GeoServer's Master Password Dump web page allows an authenticated administrator to write attacker-controlled content to any absolute filesystem path the GeoServer process can write to, including JSP files in a Tomcat webapps directory. Because GeoServer enforces no maximum master password length, an admin can embed malicious JSP code into the master password and dump it to an executable location, escalating to remote code execution on the host. No public exploit identified at time of analysis and the issue is not in CISA KEV. HIGH 7.2 0.1% 36
CVE-2026-4527 Cross-Site Request Forgery in GitLab CE/EE allows an unauthenticated attacker to create unauthorized Jira subscriptions within a targeted authenticated user's namespace by tricking the victim into clicking a specially crafted link. All GitLab installations from version 11.10 through the pre-patch 18.x releases are affected across both Community and Enterprise editions. No public exploit exists and this is not listed in CISA KEV; however, the broad version range spanning over seven years of releases and the prevalence of Jira integrations in enterprise GitLab deployments make patching a meaningful priority. MEDIUM 6.5 0.0% 33
CVE-2026-6673 Missing authentication on the Atlassian Connect install callback in Mattermost allows a remote attacker to inject a rogue sharedSecret into an in-progress Jira integration setup. Affected versions span the 10.11.x, 11.5.x, 11.6.x, and 11.7.x release trains, all of which expose the POST /ac/installed endpoint without validating the caller's identity during the pending-install window. No public exploit has been identified at time of analysis, but a successful injection corrupts the integration's trust handshake, yielding high integrity and availability impact against the Jira connection. The vendor CVSS vector assigns PR:L, which conflicts with the description's 'remote unauthenticated attacker' language - this discrepancy warrants direct verification with Mattermost advisory MMSA-2026-00654. MEDIUM 6.4 0.2% 32
No patch
CVE-2026-3160 GitLab's Jira integration exposes out-of-scope Jira issues to authenticated GitLab users across all editions (CE and EE) from version 13.7 through the patched releases, due to the integration's project-scope filter operating only as a UI display control rather than an enforced access boundary. The Changed scope (S:C) in the CVSS vector reflects that impact crosses into Atlassian Jira - a component outside GitLab's own trust domain - allowing confidential Jira issue data to leak beyond intended project boundaries. No public exploit exists and no active exploitation has been confirmed; EPSS is negligible at 0.01% (3rd percentile), placing this firmly in low-exploitation-probability territory despite a broad version range spanning over five years of releases. MEDIUM 5.8 0.0% 29
CVE-2026-48206 Authorization bypass in Apache Camel's camel-jira component (versions 4.0.0 through pre-4.21.0) allows unauthenticated HTTP clients - in routes that bridge an HTTP consumer to a jira: producer - to drive arbitrary JIRA issue operations using the endpoint's configured service-account credentials, including deleting or transitioning issues, creating issues in unauthorized projects, modifying fields, and manipulating watchers. The root cause is that JIRA control header constants (IssueKey, ProjectKey, IssueTransitionId, linkType, and others) use non-Camel-prefixed string values, bypassing the HttpHeaderFilterStrategy which only guards the 'Camel/'/'camel' header namespace at the HTTP boundary. Fixes are confirmed in 4.14.8, 4.18.3, and 4.21.0; no public exploit has been identified at time of analysis, and this vulnerability is not listed in CISA KEV. MEDIUM 5.3 0.2% 27
CVE-2026-48047 Path traversal in XWiki Platform's WebJars API enables a subwiki admin who can publish and install a malicious WebJar extension to write arbitrary files anywhere on the server filesystem. The affected Maven component `xwiki-platform-webjars-api` fails to validate that JAR entry paths extracted during extension installation remain within the intended export directory, allowing overwrite of configuration files or potential superadmin credential manipulation. No public exploit is identified and no CISA KEV listing exists; vendor-released patches are available across three version branches. MEDIUM &ndash; 0.1% &ndash;
