Top Risky CVEs
| CVE | Summary | Severity | CVSS | EPSS | Priority | Signals |
|---|---|---|---|---|---|---|
| CVE-2026-40858 | Unsafe Java deserialization in Apache Camel's camel-infinispan component allows arbitrary code execution when the ProtoStream-based remote aggregation repository reads objects from an Infinispan cache using java.io.ObjectInputStream with no ObjectInputFilter applied. Any attacker able to write to the backing Infinispan cache can plant a malicious serialized gadget that executes in the application context during routine get/recover operations. Publicly available exploit code exists, though EPSS is low (0.08%) and there is no evidence of active exploitation. | HIGH | 8.8 | 0.1% | 64 |
PoC
|
| CVE-2026-27826 | Unauthenticated attackers can abuse the MCP Atlassian server to perform arbitrary outbound HTTP requests by manipulating HTTP headers, enabling credential theft from cloud instance metadata endpoints or internal network reconnaissance without requiring authentication. The vulnerability exists in the HTTP middleware layer prior to version 0.17.0, affecting Atlassian Confluence and Jira deployments. No patch is currently available. | HIGH | 8.2 | 0.0% | 61 |
PoC
|
| CVE-2026-73498 | Arbitrary file read via path traversal in mcp-atlassian prior to 0.22.0 allows any authenticated MCP client to supply an absolute or traversal path to the confluence_upload_attachment tool, causing the server to open and exfiltrate the targeted file as a Confluence attachment. On Linux deployments, /proc/self/environ exposes live API credentials including CONFLUENCE_API_TOKEN, AWS keys, and database passwords, enabling full Atlassian account takeover and lateral movement. A confirmed prompt injection attack chain means threat actors who can write content an AI agent will read - such as a malicious Jira ticket - can trigger the same credential exfiltration with zero MCP credentials; publicly available exploit code and a demonstration video exist. | HIGH | 7.7 | 0.3% | 59 |
PoC
|
| CVE-2026-69257 | SSRF protection bypass in Flowise (npm/flowise ≤ v3.1.2) allows complete circumvention of all IPv4 CIDR deny rules via IPv4-mapped IPv6 addresses, rendering the SSRF fix introduced in v3.0.13 for CVE-2026-31829 entirely ineffective. An attacker who controls DNS for a hostname referenced in a Flowise chatflow HTTP component can set a AAAA record to `::ffff:169.254.169.254` or any RFC1918 target; Flowise resolves the address, the `isDeniedIP()` kind mismatch silently skips all IPv4 CIDR checks, and the request reaches cloud IMDS endpoints or internal services. A publicly available proof-of-concept script (poc_ssrf_bypass.js) confirms the bypass against ipaddr.js@2.2.0; no CISA KEV listing has been identified at time of analysis. | HIGH | 7.6 | 0.2% | 58 |
PoC
|
| CVE-2026-54660 | Credential exfiltration in swagger-typescript-api (npm, versions <= 13.12.1) allows a malicious OpenAPI spec to steal a developer's bearer token during code generation: when `--authorizationToken` is set, the generator attaches that token to the Authorization header of every request it makes while resolving external `$ref` URLs, with no same-origin check, so a `$ref` pointing at an attacker-controlled host receives the token verbatim. The stolen credential is typically high-value (GitHub PAT, OAuth bearer, CI service-account token) and its capture is equivalent to full account/scope takeover. A working proof-of-concept was supplied by the reporter (publicly available exploit code exists); it is not listed in CISA KEV and there is no evidence of active exploitation. | HIGH | 7.4 | 0.2% | 57 |
PoC
|
| CVE-2026-41103 | Authentication bypass in Microsoft's SAML SSO plugins for Atlassian Jira (versions 1.0.0 through 1.3.2) and Confluence (versions 1.0.0 through 7.3.x) allows a remote, unauthenticated attacker to impersonate other users and elevate privileges over the network due to an incorrectly implemented authentication algorithm. Rated CVSS 9.1 with full confidentiality and integrity impact, the flaw is deemed automatable with total technical impact by CISA's SSVC framework, though EPSS remains low (0.12%) and no public exploit has been identified at time of analysis. A vendor patch is available. | 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 | – | 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-2026-21580 | Stored cross-site scripting combined with privilege escalation in Confluence Data Center and Server lets an unauthenticated attacker persist malicious HTML/JavaScript that runs in a victim's browser, enabling actions performed as a higher-privileged user and abuse of insecure default configurations. Atlassian rates it Critical (vendor CVSS 4.0 score 9.3; the advisory body text separately cites 8.6), and it affects a long list of 7.x through 10.2.x branches. There is no public exploit identified at time of analysis and it is not on CISA KEV; it was found through Atlassian's bug bounty program. | CRITICAL | 9.3 | 0.4% | 47 |
No patch
|
| CVE-2026-27825 | MCP Atlassian server has a path traversal vulnerability enabling unauthorized access to Confluence and Jira data outside the intended scope. | CRITICAL | 9.0 | 0.0% | 45 |
PoC
|
| CVE-2026-21582 | Broken authentication in Atlassian Crowd Data Center 7.2.1 permits a remote, unauthenticated attacker to perform actions on behalf of any other user, effectively bypassing the platform's identity and session controls. The flaw was introduced specifically in version 7.2.1, discovered through Atlassian's Penetration Testing program, and carries a CVSS 4.0 score of 8.8 with scope-changing impact that cascades to all downstream SSO-federated applications. No active exploitation (CISA KEV) and no public exploit code have been identified at time of analysis, though the cross-system propagation potential demands urgent patching. | HIGH | 8.8 | 0.4% | 44 |
No patch
|
| CVE-2026-2370 | Improper authorization in GitLab CE/EE Jira Connect integration allows authenticated users with minimal workspace permissions to steal installation credentials and impersonate the GitLab application. Affects versions 14.3 through 18.8.6, 18.9.0-18.9.2, and 18.10.0. Vendor-released patches available in versions 18.8.7, 18.9.3, and 18.10.1. High CVSS score (8.1) reflects significant confidentiality and integrity impact with low attack complexity. No public exploit identified at time of analysis, though detailed disclosure exists via HackerOne report. | HIGH | 8.8 | 0.0% | 44 |
|
| 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-2026-21570 | Remote code execution in Atlassian Bamboo Data Center versions 9.6.0 through 12.1.0 allows authenticated attackers with high privileges to execute arbitrary code on affected systems with a CVSS score of 8.6. The vulnerability impacts multiple major versions with no patch currently available, requiring immediate upgrade to patched releases such as 9.6.24, 10.2.16, or 12.1.3. Organizations unable to upgrade should prioritize access controls for high-privileged accounts until remediation is possible. | HIGH | 8.6 | 0.6% | 44 |
