CVE-2026-63115

ActivityPub Undo handler can unfollow or remove reposts on behalf of other accounts

ActivityPub is a multi-tenant ActivityPub server for Ghost, built with Fedify. From 1.0.0 until 1.2.6, the `Undo` handler allows a remote federated server to cause the service to act on a `follow` or `repost` as though the activity came from a different account. This permits removal of an existing `follow` relationship or `repost` belonging to another account without that account's involvement. No private data is exposed and content is not modified; the affected relationships can be re-established. Services proxying to Ghost's hosted ActivityPub server have already been updated, while self-hosted services require an updated image and redeployment. This issue is fixed in version 1.2.6.

CVE-2026-62991

Shopper: customer detail IDOR exposes administrator and staff records

Shopper is a Headless e-commerce Admin Panel. Prior to 2.10.1, the customer detail route `/cpanel/customers/{user}/show` in `packages/admin/src/Livewire/Pages/Customers/Show.php` checks `read_customers` but looks up an arbitrary user ID without applying the `customers` role scope used by the listing. Authenticated staff holding `access_dashboard` and `read_customers` can change the user ID to retrieve administrator or staff profiles despite lacking `view_users`, which protects the separate team-management interface. The flaw exposes account profile data and permits user-ID enumeration through differing success, denial, and not-found responses. If the same role also holds `delete_customers`, `anonymizeAction()` operates on the unrestricted loaded user model and can enable destructive follow-up against non-customer accounts. This issue is fixed in version 2.10.1.

Asterisk: Heap-use-after-free in Asterisk PJSIP TCP/SDP handling when TCP connection closes during SDP processing

Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, an authenticated attacker may cause a heap-use-after-free in `PJSIP TCP/SDP` handling by sending a `SIP INVITE` over a connection-oriented transport and disconnecting before Asterisk responds with the `200 OK`. So far, the crash has only been reproduced when Asterisk is built with `Address Sanitizer`, which detects the issue. `Address Sanitizer` is a development tool with significant performance overhead and, according to the maintainer, is not used in production systems. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.

svg-sanitizer before 1.1.0 Quadratic CPU-Exhaustion DoS via PHP-Tag Stripping Loop

svg-sanitizer from 0.5.3 before 1.1.0 contains a denial of service vulnerability in Sanitizer::sanitize() that repeatedly rescans the whole input while stripping PHP tags. Unauthenticated attackers can upload SVGs with many overlapping PHP tag openers and closers, forcing quadratic preg_replace passes that exhaust worker CPU for minutes.

REDAXO Core 5.3.0 before 5.21.4 Authentication Bypass via History Plugin

REDAXO core from 5.3.0 before 5.21.4 contains an authentication bypass vulnerability in the structure/history plugin that allows unauthenticated attackers to forge temporary login tokens. Attackers can force the session-tied secret into a predictable state and forge tokens for accounts like admin, gaining backend access and code execution outside live mode.

REDAXO core before 5.21.4 contains a missing authorization vulnerability in the structure/version and structure/history frontend preview modes, which do not check category or clang permissions for the previewed article. Any backend user, or one holding history[article_rollback], can set rex_version or rex_history_date with arbitrary article_id values to read unpublished working versions and historic or deleted content.

SemanticMediaWiki 2.5.0 before 7.3.1 Stored XSS via Special:Browse Code Property

SemanticMediaWiki from 2.5.0 before 7.3.1 contains a stored cross-site scripting vulnerability that allows users with page-edit rights to inject script through Code-typed property values. Attackers can annotate a valid JSON value embedding HTML markup, which the CodeStringValueFormatter renders unescaped on Special:Browse, executing JavaScript in viewers' sessions.

Semantic MediaWiki from 3.1.0 before 7.3.1 contains a reflected cross-site scripting vulnerability in the Special:SMWAdmin ID lookup that allows unauthenticated attackers to inject markup through the unescaped id parameter. Attackers can lure an smw-admin administrator into opening a crafted lookup link, bypassing the auto-satisfied edit-token check, to execute script and perform privileged actions in the administrator's session.

Semantic MediaWiki from 3.0.0 before 7.3.1 contains a cross-site scripting vulnerability that allows attackers to inject markup by storing malicious semantic property values rendered unescaped in autocomplete suggestions. When another user opens the property-value autocomplete with an empty query, jquery.autocomplete.js concatenates the raw PValueLookup API value into HTML via container.html(), altering the dropdown and potentially executing script.
