CVE-2026-102407 - Incorrect Authorization in Elasticsearch Leading to Unauthorized Data Stream Modification

CVE ID :CVE-2026-102407
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Incorrect Authorization (CWE-863) in Elasticsearch can lead to unauthorized data stream modification via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user with sufficient privileges over a single resource could use the Modify Data Streams API to modify a data stream to which they were not otherwise authorized, potentially injecting data into it or affecting its ability to be searched normally. This issue does not allow an attacker to read the contents of a data stream they do not otherwise have access to.

CVE-2026-102408 - Inefficient Regular Expression Complexity in Elasticsearch Leading to Denial of Service

CVE ID :CVE-2026-102408
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Inefficient Regular Expression Complexity (CWE-1333) in Elasticsearch can lead to denial of service via Regular Expression Exponential Blowup (CAPEC-492). The ES|QL CHUNK function's recursive chunking strategy accepts a list of user-supplied regular expressions used as text-splitting separators, without validating their computational complexity or bounding their execution time. An authenticated user with read access to any text-based index can submit a specially crafted regular expression that triggers catastrophic backtracking, consuming excessive CPU on Elasticsearch worker threads and degrading query throughput for other tenants on the affected node. The cluster does not crash as a result of this issue.

CVE-2026-102410 - Missing Authorization in Kibana Leading to Information Disclosure

CVE ID :CVE-2026-102410
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An internal API surface within the Metrics Experience feature did not enforce a Kibana-level authorization check that an equivalent, related API in the same feature did enforce. As a result, a user who held only data-store-level read access to an index, but no corresponding Kibana feature privilege, could retrieve index-derived metric data through Kibana that the properly-authorized API would otherwise have blocked.

CVE-2026-102411 - Allocation of Resources Without Limits or Throttling in Elasticsearch Leading to Denial of Service

CVE ID :CVE-2026-102411
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Allocation of Resources Without Limits or Throttling (CWE-770) in Elasticsearch can lead to Denial of Service via Excessive Allocation (CAPEC-130). Elasticsearch enforces a size limit on the user-supplied metadata field for each individual template resource, but does not limit the total memory used when multiple such resources are retrieved together. A user holding the *manage_index_templates* cluster privilege can register multiple resources each within the individual limit. Retrieving them together materializes all of their metadata values in memory at once, exhausting available heap and causing the affected node to fail with an out-of-memory error, resulting in a denial of service.

CVE-2026-102412 - Incorrect Authorization in Kibana Leading to Sensitive Information Disclosure

CVE ID :CVE-2026-102412
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Incorrect Authorization (CWE-863) in Kibana can lead to sensitive information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated Kibana user with limited Fleet management privileges could access sensitive credential material that should be restricted to users with Fleet settings administrative access. Successful exploitation could allow an attacker to obtain private cryptographic key material configured for Fleet Server host connections, potentially enabling impersonation of trusted Fleet infrastructure components in deployments where those keys are actively used.

CVE-2026-102413 - Uncaught Exception in Elastic Endpoint Leading to Denial of Service

CVE ID :CVE-2026-102413
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Uncaught Exception (CWE-248) in Elastic Endpoint can lead to denial of service via a specially crafted file name. When Elastic Defend's Elastic Endpoint component processes a file name under certain system locale configurations (including Chinese, Japanese, and Korean locales) on Windows, an unhandled exception can occur during file-path handling. This causes the Elastic Endpoint process to crash and restart repeatedly, which can degrade or disable Elastic Defend's real-time malware prevention and behavioral detection capabilities on the affected host for as long as the condition persists.

CVE-2026-103005 - Memory Allocation with Excessive Size Value in Elasticsearch Leading to Denial of Service

CVE ID :CVE-2026-103005
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Memory Allocation with Excessive Size Value (CWE-789) in Elasticsearch can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user with connector management privileges could cause the cluster to allocate an uncontrolled amount of memory when connector resources with an excessively large `description` field are created and subsequently accessed, exhausting available heap memory and crashing the affected node.

CVE-2026-103006 - Uncontrolled Recursion in Elasticsearch Leading to Denial of Service

CVE ID :CVE-2026-103006
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Uncontrolled Recursion (CWE-674) in Elasticsearch can lead to Denial of Service via a specially crafted, deeply nested request submitted to the aggregation feature of the search API. Elasticsearch contains an uncontrolled recursion weakness in its search aggregation processing. An authenticated user with read access to a single index can submit a specially crafted request containing deeply nested aggregation definitions. Processing this request triggers unbounded recursive execution that exhausts the server process's available resources, causing the affected node to terminate. The node does not recover automatically and requires manual intervention to restore service.

CVE-2026-103007 - Incorrect Authorization in Elasticsearch Leading to Privilege Escalation

CVE ID :CVE-2026-103007
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Incorrect Authorization (CWE-863) in Elasticsearch can lead to Privilege Escalation via a delegated administrative privilege whose scope is not fully enforced during authorization checks. Elasticsearch contains an incorrect authorization weakness in a configurable, non-default privilege that lets an administrator delegate limited role-management capability to another user, scoped to specific indices. The authorization check that enforces this scoping does not correctly account for a role-definition setting that can expand the matched index set. A user holding this delegated privilege with a broadly-scoped index pattern can exploit this inconsistency by updating their own assigned role to gain access to indices that should remain restricted, including internal security data. This can enable further escalation up to full administrative control of the cluster.

CVE-2026-103008 - Uncontrolled Recursion in Elasticsearch Leading to Denial of Service

CVE ID :CVE-2026-103008
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Uncontrolled Recursion (CWE-674) in Elasticsearch can lead to Denial of Service via a specially crafted request that causes the server to construct and process a deeply nested data structure with no bound on recursion depth. Elasticsearch contains an uncontrolled recursion weakness in how it builds and serializes geometry values produced by scripted runtime fields. Unlike geometry supplied as text, which is subject to a nesting-depth limit, geometry constructed from a script's output is not bounded. An authenticated user with read access to a single index can submit a request defining such a field with a script that produces a deeply nested structure. Processing this request recurses past the available stack space, causing the affected node to terminate. The node does not recover automatically on all deployments and may require manual intervention to restore service.

CVE-2026-103009 - Authorization Bypass Through User-Controlled Key in Elasticsearch Leading to Information Disclosure

CVE ID :CVE-2026-103009
Published : Oct. 6, 2026, 7:31 p.m. | 17 minutes ago
Description :Authorization Bypass Through User-Controlled Key (CWE-639) in Elasticsearch can lead to Information Disclosure via a specially crafted cross-cluster search request that references an unauthorized shard identifier. Elasticsearch contains an authorization bypass weakness in its handling of cross-cluster search requests made through the Remote Cluster Security (RCS) 2.0 model. An authorization check validates a request against one identifying attribute of the target shard, while a separate, independently-supplied identifying attribute in the same request determines which shard is actually accessed. A holder of a cross-cluster API key authorized for one index can craft a request whose two identifying attributes refer to different indices, causing the request to be authorized against an index they can access while actually operating against a different, unauthorized index. This can expose that index's document contents, field mappings, and other metadata, and in limited cases allows modification of retention-lease state on the unauthorized index.

CVE-2026-73278 - Gitea WebAuthn bypass during OAuth and OIDC sign-in

CVE ID :CVE-2026-73278
Published : Oct. 6, 2026, 7:33 p.m. | 15 minutes ago
Description :Gitea's OAuth2 and OpenID Connect sign-in paths do not require a WebAuthn challenge when WebAuthn is the account's only configured second factor. A party able to authenticate through the affected external identity flow can obtain a full session without the passkey verification enforced during password login. One affected path can also persist an external identity link, extending the compromise beyond the initial session; accounts with TOTP configured are outside the reported WebAuthn-only scenario.

CVE-2026-104048 - Sssd: sssd: authorization bypass via cross-domain username collision in hbac evaluation

CVE ID :CVE-2026-104048
Published : Oct. 6, 2026, 7:34 p.m. | 14 minutes ago
Description :A flaw was found in SSSD. In trust-enabled identity management environments, SSSD evaluates Host-Based Access Control (HBAC) rules by stripping domain qualifiers and comparing only short usernames. An authenticated user in a trusted domain who shares the same username as an authorized local account can bypass access policies and gain unauthorized access to protected services or hosts.

CVE-2026-106063 - Gimp: gimp: heap buffer overflow in dicom export on oversized image dimensions

CVE ID :CVE-2026-106063
Published : Oct. 6, 2026, 7:34 p.m. | 14 minutes ago
Description :A heap-based buffer overflow was found in GIMP’s DICOM export plug-in. When exporting an image with extremely large width and height, the export path allocates a buffer using a 32-bit width * height (and bytes-per-pixel) product that can overflow. GEGL then writes the full uncompressed extent into the undersized buffer (CWE-787), after integer overflow in the allocation size
