Agent Zero before version 1.15 contains a stored cross-site scripting vulnerability that allows attackers to execute arbitrary JavaScript in the application origin by serving SVG files through the image_get API endpoint without Content-Security-Policy, X-Content-Type-Options, or Content-Disposition headers. Attackers can place a crafted SVG file containing script tags in any path readable by the agent-zero process and lure an authenticated user to the image_get endpoint, causing the browser to execute the malicious script, steal the csrf_token cookie, and perform unauthorized API calls on behalf of the victim.

May 27, 2026opentelemetry-js is the OpenTelemetry JavaScript Client.CVE-2026-44902 · Other software · open-telemetry · reported by GitHubHigh 7.5
opentelemetry-js is the OpenTelemetry JavaScript Client. Prior to 0.217.0, a single malformed HTTP request crashes any Node.js process running the OpenTelemetry JS Prometheus exporter. The metrics endpoint (default 0.0.0.0:9464) has no error handling around URL parsing, so a request with an invalid URI causes an uncaught TypeError that terminates the process. This vulnerability is fixed in 0.217.0.

libusb before version 1.0.30 contains a one-byte out-of-bounds read vulnerability in parse_iad_array() in descriptor.c that allows attackers to trigger a denial of service by supplying a malformed USB descriptor whose bLength equals size minus one, causing the bounds check to use the original buffer size instead of the remaining size. Attackers in virtualized environments with USB passthrough can supply crafted descriptors through libusb_get_active_interface_association_descriptors or libusb_get_interface_association_descriptors to read one byte past the end of the malloc allocation, resulting in a denial of service.

May 27, 2026In the Linux kernel, the following vulnerability has been resolved: udf: fix partition descriptor append bookkeeping Mounting a crafted UDF image with repeateCVE-2026-45991 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67High 7.8
In the Linux kernel, the following vulnerability has been resolved: udf: fix partition descriptor append bookkeeping Mounting a crafted UDF image with repeated partition descriptors can trigger a heap out-of-bounds write in part_descs_loc[]. handle_partition_descriptor() deduplicates entries by partition number, but appended slots never record partnum. As a result duplicate Partition Descriptors are appended repeatedly and num_part_descs keeps growing. Once the table is full, the growth path still sizes the allocation from partnum even though inserts are indexed by num_part_descs. If partnum is already aligned to PART_DESC_ALLOC_STEP, ALIGN(partnum, step) can keep the old capacity and the next append writes past the end of the table. Store partnum in the appended slot and size growth from the next append count so deduplication and capacity tracking follow the same model.

The Gutenverse plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions up to, and including, 3.4.6 due to insufficient input sanitization and output escaping.

May 27, 2026WPBakery Page Builder Addons by Livemesh: Stored Cross-Site ScriptingCVE-2026-2030 · WordPress plugins & themes · reported by WordfenceMedium 6.4
The WPBakery Page Builder Addons by Livemesh plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `[lvca_carousel]` and `[lvca_posts_carousel]` shortcode attributes in all versions up to, and including, 3.9.4 due to insufficient input sanitization and output escaping. Specifically, shortcode attributes are encoded with `wp_json_encode()` and output into single-quoted `data-settings` HTML attributes without using `esc_attr()`, allowing attackers to break out of the attribute by injecting single quotes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
