| CVE-2025-55197 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 7.5 High |
| pypdf is a free and open-source pure-python PDF library. Prior to version 6.0.0, an attacker can craft a PDF which leads to the RAM being exhausted. This requires just reading the file if a series of FlateDecode filters is used on a malicious cross-reference stream. Other content streams are affected on explicit access. This issue has been fixed in 6.0.0. If an update is not possible, a workaround involves including the fixed code from pypdf.filters.decompress into the existing filters file. | ||||
| CVE-2023-46250 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 5.1 Medium |
| pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions 3.7.0 through 3.16.4 can craft a PDF which leads to an infinite loop. This infinite loop blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. That is, for example, the case when the pypdf-user manipulates an incoming malicious PDF e.g. by merging it with another PDF or by adding annotations. The issue was fixed in version 3.17.0. As a workaround, apply the patch manually by modifying `pypdf/generic/_data_structures.py`. | ||||
| CVE-2023-36807 | 2 Py-pdf, Pypdf Project | 2 Pypdf, Pypdf | 2026-11-02 | 6.2 Medium |
| pypdf is a pure-python PDF library capable of splitting, merging, cropping, and transforming the pages of PDF files. In version 2.10.5 an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This infinite loop blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. That is, for example, the case if the user extracted metadata from such a malformed PDF. Versions prior to 2.10.5 throw an error, but do not hang forever. This issue was fixed with https://github.com/py-pdf/pypdf/pull/1331 which has been included in release 2.10.6. Users are advised to upgrade. Users unable to upgrade should modify `PyPDF2/generic/_data_structures.py::read_object` to an an error throwing case. See GHSA-hm9v-vj3r-r55m for details. | ||||
| CVE-2023-36464 | 2 Py-pdf, Pypdf2 Project | 2 Pypdf, Pypdf2 | 2026-11-02 | 6.2 Medium |
| pypdf is an open source, pure-python PDF library. In affected versions an attacker may craft a PDF which leads to an infinite loop if `__parse_content_stream` is executed. That is, for example, the case if the user extracted text from such a PDF. This issue was introduced in pull request #969 and resolved in pull request #1828. Users are advised to upgrade. Users unable to upgrade may modify the line `while peek not in (b"\r", b"\n")` in `pypdf/generic/_data_structures.py` to `while peek not in (b"\r", b"\n", b"")`. | ||||
| CVE-2025-62708 | 2 Py-pdf, Pypdf Project | 2 Pypdf, Pypdf | 2026-11-02 | 7.5 High |
| pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing the content stream of a page using the LZWDecode filter. This has been fixed in pypdf version 6.1.3. | ||||
| CVE-2025-62707 | 2 Py-pdf, Pypdf Project | 2 Pypdf, Pypdf | 2026-11-02 | 7.5 High |
| pypdf is a free and open-source pure-python PDF library. Prior to version 6.1.3, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page which has an inline image using the DCTDecode filter. This has been fixed in pypdf version 6.1.3. | ||||
| CVE-2023-36810 | 1 Py-pdf | 1 Pypdf | 2026-11-02 | 6.2 Medium |
| pypdf is a pure-python PDF library capable of splitting, merging, cropping, and transforming the pages of PDF files. An attacker who uses this vulnerability can craft a PDF which leads to unexpected long runtime. This quadratic runtime blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. This issue has been addressed in PR 808 and versions from 1.27.9 include this fix. Users are advised to upgrade. There are no known workarounds for this vulnerability. | ||||
| CVE-2026-119206 | 2 Py-pdf, Pypdf Project | 2 Pypdf, Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.21.3, pypdf can take excessive time to retrieve page labels from a crafted PDF containing a flat page-label number tree with many ranges. The page_labels property resolves each page independently and repeatedly scans the same /Nums array from the beginning, causing work to grow with both the page count and the number of label ranges. This issue is fixed in version 6.21.3. | ||||
| CVE-2026-119205 | 2 Py-pdf, Pypdf Project | 2 Pypdf, Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.21.4, pypdf can enter an infinite loop when cloning or duplicating a crafted cyclic DictionaryObject. Clone traversal checked generated destination references rather than the original source references, allowing some source cycles to evade the visited-object check. This issue is fixed in version 6.21.4. | ||||
| CVE-2026-119204 | 2 Py-pdf, Pypdf Project | 2 Pypdf, Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.21.4, pypdf can consume excessive memory while parsing a crafted PDF page tree containing many shared resources. Page-tree flattening copies page dictionary and inherited resource entries without a document-wide entry budget, allowing the crafted resource structure to cause disproportionate allocations. This issue is fixed in version 6.21.4. | ||||
| CVE-2026-119203 | 2 Py-pdf, Pypdf Project | 2 Pypdf, Pypdf | 2026-11-02 | 5.5 Medium |
| pypdf is a free and open-source pure-python PDF library. Prior to 6.21.4, pypdf can enter an infinite loop while opening a crafted incomplete PDF whose standard cross-reference table reaches the end of the file without a trailer. The trailer search can repeatedly rewind to the same stream position instead of terminating when parsing makes no progress, blocking the processing thread. This issue is fixed in version 6.21.4. | ||||
| CVE-2026-120461 | 1 Dromara | 1 Jpom | 2026-11-02 | 8.8 High |
| Jpom through 2.11.12 contains a cross-workspace authorization bypass in POST /node/ssh_command/batch that resolves command templates and SSH nodes by ID without workspace filtering. Authenticated users with SSH command execute permission in one workspace can supply foreign template and node IDs to run commands on other workspaces' SSH hosts using their stored credentials. | ||||
| CVE-2026-81665 | 2 Corosync, Redhat | 10 Corosync, Enterprise Linux, Enterprise Linux Eus and 7 more | 2026-11-02 | 7.5 High |
| A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control. | ||||
