Weekly CVE digest

One email a week with newly published vulnerabilities worth knowing about. No account needed.

This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.

I agree to receive the weekly CVE digest at the address above. I can withdraw this consent at any time using the link in the footer of every message.

CVE-2026-90786
Medium

A vulnerability was determined in Dvidelabs flatcc up to 0.6.3. This impacts the function align_order_members of the file src/compiler/semantics.c of the component Duplicate Symbol Handler. This manipulation causes reachable assertion. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. Patch name: 8b19ba4e992ebcad7f5970704d1afc5507fa5205. To fix this issue, it is recommended to deploy a patch.

CVE-2026-90785
Medium

A vulnerability was found in Dvidelabs flatcc up to 0.6.3 in the analyze_struct function of src/compiler/semantics.c. Manipulation leads to a reachable assertion. The attack can be launched remotely and the exploit has been made public.

CVE-2026-86349
Medium

Mattermost versions 11.9.x <= 11.9.0, 11.8.x <= 11.8.4, 11.7.x <= 11.7.8, and 10.11.x <= 10.11.22 fail to limit nesting depth in the server-side Markdown parser, allowing an authenticated attacker to cause denial of service (CPU exhaustion) via a crafted post with deeply nested blockquotes or list items.

CVE-2026-86348
Medium

Mattermost versions <=11.9, 11.0.9, 11.4.8, 11.7.7, and 10.22.11.0 fail to recover from handler panics, allowing an authenticated user to crash the plugin via a post-action request with an unexpected field type.

CVE-2026-84179
Medium

Vulnerability in Apache Storm allows unauthorized users to read credential data (e.g., storm.zookeeper.auth.payload, keystore/truststore passwords) via the topology API, because Nimbus daemon configuration is merged with topology configuration and returned without redaction.

CVE-2026-82920
Medium

Mattermost versions 11.9.x <= 11.9.0, 11.8.x <= 11.8.4, and 11.7.x <= 11.7.7 fail to enforce authorization boundaries on the access control policy update endpoint, allowing a channel or team administrator to detach a system-assigned ABAC parent policy via a crafted PUT /api/v4/access_control_policies request with an empty imports list.

CVE-2026-82441
Critical

A vulnerability in Apache Storm allows a topology submitter to delete blobs belonging to other topologies by listing their keys in `dependency_jars` and `dependency_artifacts`. Additionally, missing validation can cause Nimbus to fail to retain leadership, rendering the cluster inoperative.

CVE-2026-82439
Critical

The DRPC server in Apache Storm keeps a map from function names to request queues, and entries are never removed. An attacker can send arbitrary function names without authentication (as `drpc.authorizer` is disabled by default), leading to unbounded memory growth and eventual heap exhaustion.

CVE-2026-7208
Medium

Yealink SIP-T33G firmware versions 124.86.x.x prior to 124.87.0.0 contain a race condition vulnerability that allows authenticated attackers to interrupt active diagnostic processes by concurrently deleting output files written to predictable paths under the diagnostic directory. Attackers can trigger a diagnostic operation such as traceroute or ping and simultaneously invoke the file deletion endpoint to terminate the running process, leaving the system in an inconsistent state.

CVE-2026-73370
Critical

An incorrect authorization vulnerability in Apache Syncope affects the Reconciliation service (pull and push). Due to incomplete delegated administration security checks, calls by administrators lacking proper entitlements may be accepted, enabling unauthorized actions.

CVE-2026-73236
High

An incorrect authorization vulnerability in Apache Syncope stems from flawed implementation of Realm hierarchy-based checks. Permission enforcement uses prefix matching, making it impossible to correctly distinguish between two sibling Realms whose names begin with the same string, leading to unauthorized access.

CVE-2026-73195
High

Improper Encoding or Escaping of Output vulnerability in Apache Syncope. Authenticated users can store a spreadsheet formula payload in one of their own plain attributes. When such users are included in a CSV export and the generated CSV file is opened by a spreadsheet application, the formula may be executed. This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 through 4.0.7, from 4.1.0-M0 through 4.1.2. Users are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue.

CVE-2026-73191
Medium

An Open Redirect vulnerability in Apache Syncope affects the SRA (Syncope REST API) when configured for CAS authentication. The target Apereo CAS instance's URL is calculated unconditionally from client-supplied forwarded HTTP headers, allowing an attacker to control the redirect destination.

CVE-2026-90957
Medium

Affected versions of MISP serve uploaded SVG images inline without a restrictive browser sandbox. Malicious scripts inside SVG can execute when the SVG is navigated to directly or embedded as a document, running on the MISP origin with the viewer's session. This affects organisation SVG logos and event-report SVG pictures. The vulnerable behavior is on the serve path, not merely the upload path. Version affected: ≤2.5.45.

CVE-2026-90955
Medium

Affected versions of MISP's interactive CLI shell do not reliably preserve the identity of the impersonated MISP user across audit logging. The legacy SysLogLogable behavior stored that identity in behavior-instance state that could be overwritten when another model lazily attached the shared behavior. Consequently, subsequent CLI writes could lose the intended user attribution and be logged incorrectly. The commit also notes that CLI-originated records lacked a CLI marker, making them appear similar to ordinary web actions by that user. Version affected: ≤2.5.45.

CVE-2026-90938
High

LangBot's plugin runtime (pip package langbot_plugin) through version 0.4.17 starts a debug WebSocket server on 0.0.0.0:5401 with authentication based on a key that defaults to an empty string and is never set. A remote attacker can register an arbitrary 'debug plugin' without credentials, receive full context of IM messages, inject forged replies, send messages as bots, read knowledge bases, and register malicious tools.

CVE-2026-90937
Critical

Froxlor versions before 2.2.5 fail to validate newline characters in subdomain redirect URLs, allowing authenticated customers to inject arbitrary nginx or Apache configuration directives. Malicious URLs containing literal newlines are written verbatim into vhost config files during cron rebuild, enabling web server configuration corruption, denial of service, or hijacking of HTTP responses across hosted domains.

CVE-2026-90936
Medium

Froxlor before 2.3.7 fails to properly scope sender alias lookups to the current customer in customer_email.php. Authenticated attackers can enumerate global sender alias IDs and read other customers' allowed sender values by supplying arbitrary senderid parameters in delete confirmation requests.

CVE-2026-90935
Medium

Froxlor before 2.3.7 fails to validate the mysql_server parameter against a customer's allowed_mysqlserver allowlist in the Mysqls.add API command. Attackers can supply a disallowed server index to create MySQL databases and users on forbidden servers, bypassing per-customer access controls.

CVE-2026-90934
Medium

EspoCRM before 10.0.4 contains a field-level security bypass vulnerability in the meeting and call attendees endpoints that allows authenticated users to read restricted email addresses. Attackers can recover hidden attendee emails by exploiting incorrect ACL scope validation that checks parent event permissions instead of attendee entity permissions.
