Incorrect authorization in JetBrains YouTrack before versions 2025.3.160480 and 2026.1.14047 allows authenticated low-privilege users to modify linked issue entities they lack update permission on by issuing PUT requests directly to link sub-resources. The flaw bypasses YouTrack's permission model at the HTTP method level, enabling integrity violations across project boundaries-reflected in the CVSS scope change (S:C). No public exploit code or active exploitation has been identified at time of analysis.
Unauthorized integrity modification in JetBrains YouTrack before 2026.2.18634 allows any authenticated low-privilege user to alter links on issues they are explicitly prohibited from accessing by exploiting the whiteboard clone operation. The whiteboard clone workflow fails to validate the cloning user's authorization against issues referenced in the board, enabling cross-boundary write access governed by CWE-862 (Missing Authorization). No public exploit has been identified at time of analysis, but the CVSS 7.7 vector (S:C, I:H, PR:L, AC:L) accurately reflects the low barrier to exploitation and the cross-domain integrity impact.
Cross-tenant GitHub App installation token theft in JetBrains YouTrack before 2026.2.18634 lets any authenticated user retrieve GitHub App installation tokens belonging to other tenants due to a shared, non-isolated token cache. The root cause is CWE-488 (Exposure of Data Element to Wrong Session): cached tokens were keyed without tenant-scope isolation. With a stolen installation token, an attacker can authenticate to the GitHub API as the victim organization's GitHub App, gaining access to that organization's repositories, pull requests, issues, and CI/CD integrations; no public exploit has been identified at time of analysis.
Privilege escalation in JetBrains YouTrack before version 2026.2.18634 enables authenticated low-privileged users to alter group memberships without proper server-side authorization validation, effectively granting themselves elevated rights. The flaw (CWE-266, Incorrect Privilege Assignment) means the application trusts client-supplied group membership parameters without enforcing that the requesting user has the authority to make such changes. With a CVSS base score of 8.8 and full C:H/I:H/A:H impact, successful exploitation yields the equivalent of full administrative control over the YouTrack instance.
Missing authorization in JetBrains YouTrack's REST API allows authenticated low-privileged users to access and modify restricted resources via Insecure Direct Object Reference (IDOR). Affected versions span all YouTrack releases prior to 2026.2.18788, 2026.1.14055, and 2025.3.161254 across three active release branches. An attacker with any valid account can enumerate or directly reference object identifiers in REST API calls to read or write data they should not have access to, with high confidentiality and integrity impact per the CVSS vector.
Unauthenticated account takeover in JetBrains YouTrack's Helpdesk feature allows a remote attacker to hijack existing accounts by asserting a victim's email address without proving ownership of it. All YouTrack builds before 2025.3.161254 and 2026.1.14042 are affected. Because the flaw is a trust failure in how Helpdesk associates a self-provided email with an account, exploitation requires no credentials, no user interaction, and works against default configurations where Helpdesk is enabled. No public exploit identified at time of analysis.
Authentication bypass in JetBrains YouTrack allows attackers to obtain full administrative access by leveraging a direct-database-access code path, per CWE-306 (missing authentication for a critical function). All self-hosted YouTrack builds prior to the 2026.1.13757 / 2025.3.148033 / 2025.2.148048 / 2025.1.148120 / 2024.3.148430 / 2024.2.148429 fix trains are affected, and JetBrains rates it CVSS 10.0. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the maximal severity score and administrative impact make prompt patching essential.
Prototype pollution in JetBrains YouTrack's websandbox bridge (all versions before 2026.2.16593) lets an attacker who can reach the sandbox boundary corrupt JavaScript Object.prototype, potentially escaping the sandbox or disclosing information. The flaw was internally reported by JetBrains and classed as CWE-1321; it carries a vendor-published CVSS of 9.8, but no public exploit has been identified at time of analysis and EPSS rates exploitation probability low at 0.40% (32nd percentile).
Improper authorization in JetBrains YouTrack's app configurations endpoint lets remote attackers modify project settings they should not be permitted to change, affecting all versions before 2026.2.16593. The flaw (CWE-862, Missing Authorization) impacts integrity only - no data disclosure or service disruption - and was self-reported by JetBrains with a patch already available. No public exploit identified at time of analysis, and EPSS exploitation probability is low (0.16%, 5th percentile).
Information disclosure in JetBrains YouTrack before 2026.2.16593 allows remote attackers to read other users' private data through a missing authorization check on the comment templates endpoint. The flaw is unauthenticated and network-reachable per the CVSS vector (PR:N), exposing confidential information without any user interaction. There is no public exploit identified at time of analysis, and the EPSS probability is low (0.16%, 6th percentile).
Information disclosure in JetBrains YouTrack before 2026.1.13162 allows remote unauthenticated attackers to obtain sensitive data through fetchApp requests. The flaw exposes confidential information without requiring authentication or user interaction, but carries no integrity or availability impact. There is no public exploit identified at time of analysis, and the EPSS score of 0.00% reflects no observed exploitation activity.
Sandbox escape in JetBrains YouTrack before 2025.3.131383 allows high-privileged users to execute arbitrary code on the server. The vulnerability affects all YouTrack versions prior to 2025.3.131383 and is classified as both an authentication bypass and server-side template injection (SSTI). EPSS scoring indicates 0% exploitation probability with no evidence of active exploitation or public POCs. Despite a CVSS score of 7.2, the requirement for high-level administrative privileges significantly constrains real-world attack surface to insider threats or compromised admin accounts.
Authenticated users in JetBrains YouTrack versions prior to 2025.3.121962 can bypass authorization controls to access the app permissions endpoint, potentially allowing privilege escalation or unauthorized modification of application settings. This vulnerability requires valid login credentials but has no complexity requirements, enabling attackers with low-level access to gain high-impact capabilities including confidentiality and integrity violations. No patch is currently available.
Privilege escalation in JetBrains YouTrack before version 2026.1.14047 allows an authenticated user holding project update permissions to grant themselves the Project Admin role without proper authorization. The vulnerability stems from a missing escalation check (CWE-266: Incorrect Privilege Assignment) in the project permissions workflow, enabling a project contributor to cross a privilege boundary and assume administrative control over a project. No active exploitation has been confirmed (not listed in CISA KEV), and no public exploit code is known at time of analysis.
Authenticated users in JetBrains YouTrack before 2026.1.14047 can enumerate all group names via predefined search fields, bypassing group visibility permissions enforced elsewhere in the product. The flaw (CWE-862 Missing Authorization) means the access-control check applied to group visibility was not consistently applied to the predefined search field code path, leaking organizational structure to any logged-in user. No active exploitation has been identified and no public exploit code exists; CVSS 4.3 reflects the limited confidentiality impact.
Credential exfiltration in JetBrains YouTrack before 2026.2.18769 allows a project administrator to redirect stored mailbox credentials to an attacker-controlled server by modifying the mailbox host setting without triggering re-authentication. The missing re-authentication gate means any project admin who has been compromised, is malicious, or has temporarily elevated access can silently capture email account credentials (username and password) already stored in YouTrack. No public exploit has been identified at time of analysis, and CISA has not added this to the Known Exploited Vulnerabilities catalog.
Missing authorization (CWE-862) in JetBrains YouTrack before 2026.2.18769 allows any low-privileged authenticated user to read the email addresses of Helpdesk authorized reporters, who are external contacts registered to submit issues. The flaw bypasses the intended access control on the Helpdesk reporter roster, exposing personally identifiable contact data to users who should have no visibility into it. No public exploit is identified at time of analysis, and the vulnerability has been patched by JetBrains in version 2026.2.18769.
Missing server-side permission checks in JetBrains YouTrack before 2026.2.18687 allow any authenticated user to create knowledge base articles inside projects they are not authorized to access. The flaw is rooted in CWE-862 (Missing Authorization), where the article-creation endpoint omits the necessary access control validation against the caller's project permissions. No public exploit or active exploitation has been identified; the CVSS PR:L metric confirms exploitation is limited to users who already hold a valid YouTrack account.
Improper authorization in JetBrains YouTrack before 2026.2.18634 allows authenticated read-only users to create and modify whiteboard cards, exceeding their intended permissions. The flaw (CWE-863) bypasses YouTrack's role-based access controls for the whiteboard feature, enabling low-privileged users to perform write operations they should be denied. No public exploit code or active exploitation has been identified, and a vendor-confirmed fix is available. EPSS data was not provided; real-world risk is moderate given the authentication prerequisite.
Stored cross-site scripting in JetBrains YouTrack before version 2026.2.18634 allows a high-privileged attacker to inject malicious scripts by uploading crafted project or organization icon files. When other authenticated users subsequently view the affected project or organization page, the stored payload executes in their browser context, enabling session data exposure or unauthorized in-application actions. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis.
Insufficient permission checks on the app import endpoint in JetBrains YouTrack before version 2026.2.18634 allow an authenticated low-privileged user to overwrite bundled applications, achieving high-integrity impact across all unpatched deployments. The flaw is rooted in CWE-863 (Incorrect Authorization), meaning the server fails to validate that the requesting account holds sufficient privileges for a destructive write operation against pre-installed components. No public exploit code or confirmed active exploitation has been identified at time of analysis.
Insecure Direct Object Reference (IDOR) in JetBrains YouTrack before 2026.2.18634 allows authenticated low-privileged users to enumerate and read private issues and starred folder contents belonging to other users across organizational boundaries by manipulating user profile API identifiers. The CVSS 6.5 score (AV:N/AC:L/PR:L/UI:N/C:H) reflects straightforward network exploitation requiring only a valid session. No public exploit or KEV listing is present, but the low attack complexity and high confidentiality impact make this a meaningful data-exposure risk in multi-tenant or multi-organization YouTrack deployments.
Insecure Direct Object Reference in JetBrains YouTrack before version 2026.2.18634 permits authenticated users to access other users' private saved searches through the watchRules and issueListConfig API endpoints. The endpoints fail to enforce authorization checks on user-controlled object identifiers, allowing horizontal privilege escalation without elevated permissions. No active exploitation or public proof-of-concept code has been identified at time of analysis.
Authorization bypass in JetBrains YouTrack's whiteboard feature allows authenticated read-only whiteboard users to modify canvas content they should only be able to view, by sending a crafted WebSocket message. Affected versions are all YouTrack releases before 2026.2.18634. The vulnerability stems from CWE-863 (Incorrect Authorization) - the server-side WebSocket handler fails to enforce the read-only permission boundary, accepting write operations from users who lack write privileges. No public exploit or active exploitation has been identified.
The generic VCS webhook handler in JetBrains YouTrack before 2026.2.18634 fails open when no webhook secret is configured, allowing unauthenticated remote callers to trigger webhook processing without any valid credential check. This CWE-306 flaw means that deployments where the webhook secret field is intentionally or inadvertently left blank accept all inbound webhook payloads as legitimate, bypassing the shared-secret verification mechanism. No public exploit code has been identified and the vulnerability is not in CISA KEV; the low CVSS score of 3.7 with AC:H accurately reflects that exploitation is constrained to misconfigured instances.
IP spoofing via forged HTTP headers in JetBrains YouTrack before 2026.2.18634 allows unauthenticated remote attackers to bypass Bitbucket webhook source validation, causing YouTrack to process attacker-crafted webhook payloads as if they originated from a legitimate Bitbucket server. The root cause is CWE-291 - reliance on IP address for authentication - specifically trusting client-controlled headers such as X-Forwarded-For to gate webhook acceptance. No public exploit has been identified at time of analysis, and JetBrains has released a patched build.
Stored XSS in JetBrains YouTrack before version 2026.2.18634 allows authenticated low-privilege users to inject AngularJS template expressions through issue assignee name fields, which are then evaluated as client-side JavaScript in the browsers of any user who views the affected issue or project board. The attack persists server-side, meaning every subsequent viewer triggers execution without further attacker interaction. No public exploit code or confirmed active exploitation has been identified at time of analysis.
Stored cross-site scripting in JetBrains YouTrack before version 2026.2.18634 allows authenticated low-privileged users to inject persistent malicious scripts through custom field values displayed on Agile board cards. When a victim with an active YouTrack session views the affected Agile board, the injected script executes in their browser context, enabling session hijacking, credential theft, or unauthorized actions on their behalf. No public exploit code has been identified at time of analysis, and JetBrains has released a patched version.
Signed URL reuse in JetBrains YouTrack before 2026.2.18634 permits authenticated users to access restricted project icons they are not authorized to view. The flaw arises because signed URLs generated for project icon assets are not properly scoped or invalidated, allowing the same URL to be reused beyond its intended access context. No public exploit code has been identified and the vendor has issued a patch, making this a low-urgency but straightforward authorization control deficiency in a widely used issue tracker.
Stored XSS in JetBrains YouTrack before 2026.2.17394 allows low-privileged authenticated users to inject malicious scripts into article titles, which are then rendered unsanitized within digest emails delivered to other users. When a recipient opens the digest email in an HTML-capable client and interacts with the affected content, the injected script executes in their browser context, enabling session token or credential theft. No public exploit or active exploitation has been identified; the CVSS score of 3.5 (Low) reflects the constrained impact due to required authentication, mandatory user interaction, and limited confidentiality-only impact.
CSS injection via Mermaid diagram rendering in JetBrains YouTrack before version 2026.2.17012 permits authenticated low-privilege users to embed malicious CSS into diagram content that executes in the browsers of other users who view the affected page. The CVSS score of 3.5 (Low) reflects the dual gating conditions of required authentication and victim interaction, substantially constraining real-world impact to UI manipulation rather than data exfiltration or code execution. No public exploit code or active exploitation has been identified at time of analysis.
Improper access control in JetBrains YouTrack before version 2026.2.16593 permits authenticated low-privileged users to read saved queries and tags outside their authorized scope. The flaw stems from missing authorization checks (CWE-862), meaning the application fails to verify whether the requesting user holds the required permissions before serving these resources over the network. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog, though the network-accessible nature of the issue means any authenticated user on an exposed YouTrack instance is a potential threat actor.
Excessive user profile data disclosure in JetBrains YouTrack before 2026.2.16593 results from overly permissive default role configuration, allowing any authenticated low-privilege user to read more user profile attributes than intended. The root cause is CWE-276 (Incorrect Default Permissions), where the shipped default role grants broader read access to user directory data than the principle of least privilege requires. No public exploit or confirmed active exploitation exists at time of analysis.
Project settings disclosure in JetBrains YouTrack before version 2026.2.16593 allows an authenticated low-privileged user to read project configuration data they are not authorized to access via the MCP (Model Context Protocol) integration. The root cause is a missing authorization check (CWE-862) on MCP-exposed endpoints, meaning the server returns project settings without validating the requesting user's project-level permissions. No public exploit has been identified at time of analysis, no KEV listing exists, and a vendor-released patch is available.
Improper access control in JetBrains YouTrack before 2026.1.13570 permits any authenticated low-privileged user to enumerate restricted issues and articles through the Planning Canvas feature, exposing confidential project data they are not authorized to view. Rooted in CWE-639 (Authorization Bypass Through User-Controlled Key), the flaw allows user-controlled identifiers to bypass access restrictions without proper authorization checks. No public exploit code has been identified and this vulnerability is not listed in CISA KEV at time of analysis.
Improper access control in JetBrains YouTrack before version 2026.1.13570 permits any low-privileged authenticated user to modify service accounts, an administrative operation that should be restricted to privileged roles. Rooted in CWE-862 (Missing Authorization), the flaw is exploitable over the network with low complexity, requiring no user interaction - meaning any valid account holder on an exposed instance can tamper with service account configurations. No public exploit or CISA KEV listing has been identified at time of analysis, but the integrity impact is rated high given the sensitivity of service account access in YouTrack deployments.
Information disclosure in JetBrains YouTrack before version 2026.1.13162 allows authenticated low-privilege users to access sensitive user and group membership data they are not authorized to view. Rooted in CWE-863 (Incorrect Authorization), the flaw exists on the Users and Groups administrative pages, where authorization checks are insufficiently enforced for authenticated sessions. No public exploit identified at time of analysis, and this vulnerability is not listed in CISA KEV; however, the low access complexity means any authenticated attacker can reliably reproduce the condition.
Stored cross-site scripting in JetBrains YouTrack versions prior to 2026.1.13162 allows an authenticated project-level user to inject persistent JavaScript into project notification templates, which executes in the browsers of other users who receive or view those notifications. The scope-changed CVSS 8.7 reflects that injected scripts can pivot beyond the vulnerable component to compromise the sessions and data of higher-privileged recipients. No public exploit identified at time of analysis and no KEV listing, but the issue was disclosed and patched directly by the vendor.

Incorrect authorization in JetBrains YouTrack before versions 2025.3.160480 and 2026.1.14047 allows authenticated low-privilege users to modify linked issue entities they lack update permission on by issuing PUT requests directly to link sub-resources. The flaw bypasses YouTrack's permission model at the HTTP method level, enabling integrity violations across project boundaries-reflected in the CVSS scope change (S:C). No public exploit code or active exploitation has been identified at time of analysis.
Unauthorized integrity modification in JetBrains YouTrack before 2026.2.18634 allows any authenticated low-privilege user to alter links on issues they are explicitly prohibited from accessing by exploiting the whiteboard clone operation. The whiteboard clone workflow fails to validate the cloning user's authorization against issues referenced in the board, enabling cross-boundary write access governed by CWE-862 (Missing Authorization). No public exploit has been identified at time of analysis, but the CVSS 7.7 vector (S:C, I:H, PR:L, AC:L) accurately reflects the low barrier to exploitation and the cross-domain integrity impact.
Cross-tenant GitHub App installation token theft in JetBrains YouTrack before 2026.2.18634 lets any authenticated user retrieve GitHub App installation tokens belonging to other tenants due to a shared, non-isolated token cache. The root cause is CWE-488 (Exposure of Data Element to Wrong Session): cached tokens were keyed without tenant-scope isolation. With a stolen installation token, an attacker can authenticate to the GitHub API as the victim organization's GitHub App, gaining access to that organization's repositories, pull requests, issues, and CI/CD integrations; no public exploit has been identified at time of analysis.
Privilege escalation in JetBrains YouTrack before version 2026.2.18634 enables authenticated low-privileged users to alter group memberships without proper server-side authorization validation, effectively granting themselves elevated rights. The flaw (CWE-266, Incorrect Privilege Assignment) means the application trusts client-supplied group membership parameters without enforcing that the requesting user has the authority to make such changes. With a CVSS base score of 8.8 and full C:H/I:H/A:H impact, successful exploitation yields the equivalent of full administrative control over the YouTrack instance.
Missing authorization in JetBrains YouTrack's REST API allows authenticated low-privileged users to access and modify restricted resources via Insecure Direct Object Reference (IDOR). Affected versions span all YouTrack releases prior to 2026.2.18788, 2026.1.14055, and 2025.3.161254 across three active release branches. An attacker with any valid account can enumerate or directly reference object identifiers in REST API calls to read or write data they should not have access to, with high confidentiality and integrity impact per the CVSS vector.
Unauthenticated account takeover in JetBrains YouTrack's Helpdesk feature allows a remote attacker to hijack existing accounts by asserting a victim's email address without proving ownership of it. All YouTrack builds before 2025.3.161254 and 2026.1.14042 are affected. Because the flaw is a trust failure in how Helpdesk associates a self-provided email with an account, exploitation requires no credentials, no user interaction, and works against default configurations where Helpdesk is enabled. No public exploit identified at time of analysis.
Authentication bypass in JetBrains YouTrack allows attackers to obtain full administrative access by leveraging a direct-database-access code path, per CWE-306 (missing authentication for a critical function). All self-hosted YouTrack builds prior to the 2026.1.13757 / 2025.3.148033 / 2025.2.148048 / 2025.1.148120 / 2024.3.148430 / 2024.2.148429 fix trains are affected, and JetBrains rates it CVSS 10.0. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the maximal severity score and administrative impact make prompt patching essential.
Prototype pollution in JetBrains YouTrack's websandbox bridge (all versions before 2026.2.16593) lets an attacker who can reach the sandbox boundary corrupt JavaScript Object.prototype, potentially escaping the sandbox or disclosing information. The flaw was internally reported by JetBrains and classed as CWE-1321; it carries a vendor-published CVSS of 9.8, but no public exploit has been identified at time of analysis and EPSS rates exploitation probability low at 0.40% (32nd percentile).
Improper authorization in JetBrains YouTrack's app configurations endpoint lets remote attackers modify project settings they should not be permitted to change, affecting all versions before 2026.2.16593. The flaw (CWE-862, Missing Authorization) impacts integrity only - no data disclosure or service disruption - and was self-reported by JetBrains with a patch already available. No public exploit identified at time of analysis, and EPSS exploitation probability is low (0.16%, 5th percentile).
Information disclosure in JetBrains YouTrack before 2026.2.16593 allows remote attackers to read other users' private data through a missing authorization check on the comment templates endpoint. The flaw is unauthenticated and network-reachable per the CVSS vector (PR:N), exposing confidential information without any user interaction. There is no public exploit identified at time of analysis, and the EPSS probability is low (0.16%, 6th percentile).
Information disclosure in JetBrains YouTrack before 2026.1.13162 allows remote unauthenticated attackers to obtain sensitive data through fetchApp requests. The flaw exposes confidential information without requiring authentication or user interaction, but carries no integrity or availability impact. There is no public exploit identified at time of analysis, and the EPSS score of 0.00% reflects no observed exploitation activity.
Sandbox escape in JetBrains YouTrack before 2025.3.131383 allows high-privileged users to execute arbitrary code on the server. The vulnerability affects all YouTrack versions prior to 2025.3.131383 and is classified as both an authentication bypass and server-side template injection (SSTI). EPSS scoring indicates 0% exploitation probability with no evidence of active exploitation or public POCs. Despite a CVSS score of 7.2, the requirement for high-level administrative privileges significantly constrains real-world attack surface to insider threats or compromised admin accounts.
Authenticated users in JetBrains YouTrack versions prior to 2025.3.121962 can bypass authorization controls to access the app permissions endpoint, potentially allowing privilege escalation or unauthorized modification of application settings. This vulnerability requires valid login credentials but has no complexity requirements, enabling attackers with low-level access to gain high-impact capabilities including confidentiality and integrity violations. No patch is currently available.
Privilege escalation in JetBrains YouTrack before version 2026.1.14047 allows an authenticated user holding project update permissions to grant themselves the Project Admin role without proper authorization. The vulnerability stems from a missing escalation check (CWE-266: Incorrect Privilege Assignment) in the project permissions workflow, enabling a project contributor to cross a privilege boundary and assume administrative control over a project. No active exploitation has been confirmed (not listed in CISA KEV), and no public exploit code is known at time of analysis.
Authenticated users in JetBrains YouTrack before 2026.1.14047 can enumerate all group names via predefined search fields, bypassing group visibility permissions enforced elsewhere in the product. The flaw (CWE-862 Missing Authorization) means the access-control check applied to group visibility was not consistently applied to the predefined search field code path, leaking organizational structure to any logged-in user. No active exploitation has been identified and no public exploit code exists; CVSS 4.3 reflects the limited confidentiality impact.
Credential exfiltration in JetBrains YouTrack before 2026.2.18769 allows a project administrator to redirect stored mailbox credentials to an attacker-controlled server by modifying the mailbox host setting without triggering re-authentication. The missing re-authentication gate means any project admin who has been compromised, is malicious, or has temporarily elevated access can silently capture email account credentials (username and password) already stored in YouTrack. No public exploit has been identified at time of analysis, and CISA has not added this to the Known Exploited Vulnerabilities catalog.
Missing authorization (CWE-862) in JetBrains YouTrack before 2026.2.18769 allows any low-privileged authenticated user to read the email addresses of Helpdesk authorized reporters, who are external contacts registered to submit issues. The flaw bypasses the intended access control on the Helpdesk reporter roster, exposing personally identifiable contact data to users who should have no visibility into it. No public exploit is identified at time of analysis, and the vulnerability has been patched by JetBrains in version 2026.2.18769.
Missing server-side permission checks in JetBrains YouTrack before 2026.2.18687 allow any authenticated user to create knowledge base articles inside projects they are not authorized to access. The flaw is rooted in CWE-862 (Missing Authorization), where the article-creation endpoint omits the necessary access control validation against the caller's project permissions. No public exploit or active exploitation has been identified; the CVSS PR:L metric confirms exploitation is limited to users who already hold a valid YouTrack account.
Improper authorization in JetBrains YouTrack before 2026.2.18634 allows authenticated read-only users to create and modify whiteboard cards, exceeding their intended permissions. The flaw (CWE-863) bypasses YouTrack's role-based access controls for the whiteboard feature, enabling low-privileged users to perform write operations they should be denied. No public exploit code or active exploitation has been identified, and a vendor-confirmed fix is available. EPSS data was not provided; real-world risk is moderate given the authentication prerequisite.
Stored cross-site scripting in JetBrains YouTrack before version 2026.2.18634 allows a high-privileged attacker to inject malicious scripts by uploading crafted project or organization icon files. When other authenticated users subsequently view the affected project or organization page, the stored payload executes in their browser context, enabling session data exposure or unauthorized in-application actions. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis.
Insufficient permission checks on the app import endpoint in JetBrains YouTrack before version 2026.2.18634 allow an authenticated low-privileged user to overwrite bundled applications, achieving high-integrity impact across all unpatched deployments. The flaw is rooted in CWE-863 (Incorrect Authorization), meaning the server fails to validate that the requesting account holds sufficient privileges for a destructive write operation against pre-installed components. No public exploit code or confirmed active exploitation has been identified at time of analysis.
Insecure Direct Object Reference (IDOR) in JetBrains YouTrack before 2026.2.18634 allows authenticated low-privileged users to enumerate and read private issues and starred folder contents belonging to other users across organizational boundaries by manipulating user profile API identifiers. The CVSS 6.5 score (AV:N/AC:L/PR:L/UI:N/C:H) reflects straightforward network exploitation requiring only a valid session. No public exploit or KEV listing is present, but the low attack complexity and high confidentiality impact make this a meaningful data-exposure risk in multi-tenant or multi-organization YouTrack deployments.
Insecure Direct Object Reference in JetBrains YouTrack before version 2026.2.18634 permits authenticated users to access other users' private saved searches through the watchRules and issueListConfig API endpoints. The endpoints fail to enforce authorization checks on user-controlled object identifiers, allowing horizontal privilege escalation without elevated permissions. No active exploitation or public proof-of-concept code has been identified at time of analysis.
Authorization bypass in JetBrains YouTrack's whiteboard feature allows authenticated read-only whiteboard users to modify canvas content they should only be able to view, by sending a crafted WebSocket message. Affected versions are all YouTrack releases before 2026.2.18634. The vulnerability stems from CWE-863 (Incorrect Authorization) - the server-side WebSocket handler fails to enforce the read-only permission boundary, accepting write operations from users who lack write privileges. No public exploit or active exploitation has been identified.
The generic VCS webhook handler in JetBrains YouTrack before 2026.2.18634 fails open when no webhook secret is configured, allowing unauthenticated remote callers to trigger webhook processing without any valid credential check. This CWE-306 flaw means that deployments where the webhook secret field is intentionally or inadvertently left blank accept all inbound webhook payloads as legitimate, bypassing the shared-secret verification mechanism. No public exploit code has been identified and the vulnerability is not in CISA KEV; the low CVSS score of 3.7 with AC:H accurately reflects that exploitation is constrained to misconfigured instances.
IP spoofing via forged HTTP headers in JetBrains YouTrack before 2026.2.18634 allows unauthenticated remote attackers to bypass Bitbucket webhook source validation, causing YouTrack to process attacker-crafted webhook payloads as if they originated from a legitimate Bitbucket server. The root cause is CWE-291 - reliance on IP address for authentication - specifically trusting client-controlled headers such as X-Forwarded-For to gate webhook acceptance. No public exploit has been identified at time of analysis, and JetBrains has released a patched build.
Stored XSS in JetBrains YouTrack before version 2026.2.18634 allows authenticated low-privilege users to inject AngularJS template expressions through issue assignee name fields, which are then evaluated as client-side JavaScript in the browsers of any user who views the affected issue or project board. The attack persists server-side, meaning every subsequent viewer triggers execution without further attacker interaction. No public exploit code or confirmed active exploitation has been identified at time of analysis.
Stored cross-site scripting in JetBrains YouTrack before version 2026.2.18634 allows authenticated low-privileged users to inject persistent malicious scripts through custom field values displayed on Agile board cards. When a victim with an active YouTrack session views the affected Agile board, the injected script executes in their browser context, enabling session hijacking, credential theft, or unauthorized actions on their behalf. No public exploit code has been identified at time of analysis, and JetBrains has released a patched version.
Signed URL reuse in JetBrains YouTrack before 2026.2.18634 permits authenticated users to access restricted project icons they are not authorized to view. The flaw arises because signed URLs generated for project icon assets are not properly scoped or invalidated, allowing the same URL to be reused beyond its intended access context. No public exploit code has been identified and the vendor has issued a patch, making this a low-urgency but straightforward authorization control deficiency in a widely used issue tracker.
Stored XSS in JetBrains YouTrack before 2026.2.17394 allows low-privileged authenticated users to inject malicious scripts into article titles, which are then rendered unsanitized within digest emails delivered to other users. When a recipient opens the digest email in an HTML-capable client and interacts with the affected content, the injected script executes in their browser context, enabling session token or credential theft. No public exploit or active exploitation has been identified; the CVSS score of 3.5 (Low) reflects the constrained impact due to required authentication, mandatory user interaction, and limited confidentiality-only impact.
CSS injection via Mermaid diagram rendering in JetBrains YouTrack before version 2026.2.17012 permits authenticated low-privilege users to embed malicious CSS into diagram content that executes in the browsers of other users who view the affected page. The CVSS score of 3.5 (Low) reflects the dual gating conditions of required authentication and victim interaction, substantially constraining real-world impact to UI manipulation rather than data exfiltration or code execution. No public exploit code or active exploitation has been identified at time of analysis.
Improper access control in JetBrains YouTrack before version 2026.2.16593 permits authenticated low-privileged users to read saved queries and tags outside their authorized scope. The flaw stems from missing authorization checks (CWE-862), meaning the application fails to verify whether the requesting user holds the required permissions before serving these resources over the network. No public exploit code has been identified and this vulnerability is not listed in the CISA KEV catalog, though the network-accessible nature of the issue means any authenticated user on an exposed YouTrack instance is a potential threat actor.
Excessive user profile data disclosure in JetBrains YouTrack before 2026.2.16593 results from overly permissive default role configuration, allowing any authenticated low-privilege user to read more user profile attributes than intended. The root cause is CWE-276 (Incorrect Default Permissions), where the shipped default role grants broader read access to user directory data than the principle of least privilege requires. No public exploit or confirmed active exploitation exists at time of analysis.
Project settings disclosure in JetBrains YouTrack before version 2026.2.16593 allows an authenticated low-privileged user to read project configuration data they are not authorized to access via the MCP (Model Context Protocol) integration. The root cause is a missing authorization check (CWE-862) on MCP-exposed endpoints, meaning the server returns project settings without validating the requesting user's project-level permissions. No public exploit has been identified at time of analysis, no KEV listing exists, and a vendor-released patch is available.
Improper access control in JetBrains YouTrack before 2026.1.13570 permits any authenticated low-privileged user to enumerate restricted issues and articles through the Planning Canvas feature, exposing confidential project data they are not authorized to view. Rooted in CWE-639 (Authorization Bypass Through User-Controlled Key), the flaw allows user-controlled identifiers to bypass access restrictions without proper authorization checks. No public exploit code has been identified and this vulnerability is not listed in CISA KEV at time of analysis.
Improper access control in JetBrains YouTrack before version 2026.1.13570 permits any low-privileged authenticated user to modify service accounts, an administrative operation that should be restricted to privileged roles. Rooted in CWE-862 (Missing Authorization), the flaw is exploitable over the network with low complexity, requiring no user interaction - meaning any valid account holder on an exposed instance can tamper with service account configurations. No public exploit or CISA KEV listing has been identified at time of analysis, but the integrity impact is rated high given the sensitivity of service account access in YouTrack deployments.
Information disclosure in JetBrains YouTrack before version 2026.1.13162 allows authenticated low-privilege users to access sensitive user and group membership data they are not authorized to view. Rooted in CWE-863 (Incorrect Authorization), the flaw exists on the Users and Groups administrative pages, where authorization checks are insufficiently enforced for authenticated sessions. No public exploit identified at time of analysis, and this vulnerability is not listed in CISA KEV; however, the low access complexity means any authenticated attacker can reliably reproduce the condition.
Stored cross-site scripting in JetBrains YouTrack versions prior to 2026.1.13162 allows an authenticated project-level user to inject persistent JavaScript into project notification templates, which executes in the browsers of other users who receive or view those notifications. The scope-changed CVSS 8.7 reflects that injected scripts can pivot beyond the vulnerable component to compromise the sessions and data of higher-privileged recipients. No public exploit identified at time of analysis and no KEV listing, but the issue was disclosed and patched directly by the vendor.
